Reinforcement rods or mesh are used for tensile, shear, and sometimes intense pressure in a concrete structure. Reinforced concrete is subject to many natural problems or industrial errors. The result of these problems is that it reduces the efficiency of the reinforced concrete or its usefulness. Some of these problems are cracks, earthquakes, high temperatures or fires, as well as corrosion of reinforced iron inside reinforced concrete. There are also factors of ancient buildings or monuments that require some techniques to preserve them. This research presents some general information about reinforced concrete, the pros and cons of reinforced concrete, and then presents a series of literary studies of some of the late published researches on the subject of reinforced concrete and how to preserve it, propose solutions or treatments for the treatment of reinforced concrete problems, raise efficiency and quality for a longer period. These studies have provided advanced and modern methods and techniques in the field of reinforced concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title="reinforced concrete">reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=cracks" title=" cracks"> cracks</a> </p> <a href="https://publications.waset.org/abstracts/110089/reinforced-concrete-problems-and-solutions-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110089.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4120</span> Determining Earthquake Performances of Existing Reinforced Concrete Buildings by Using ANN</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Musa%20H.%20Arslan">Musa H.

The selected parameters have been thought to be effective on the performance of RC buildings. In the performance analyses stage of the study, level of performance possible to be shown by these buildings in case of an earthquake was determined on the basis of the 4-grade performance levels specified in Turkish Earthquake Code- 2007 (TEC-2007). After obtaining the 4-grade performance level, selected 23 parameters of each building have been matched with the performance level. In this stage, ANN-based fast evaluation algorithm mentioned above made an economic and rapid evaluation of four to ten storey RC buildings.

Microtremor measurement was conducted in the main cities, Mandalay and Yangon. In order to evaluate the seismic properties of buildings currently under construction, seismic information was gathered for six buildings in Yangon city and four buildings in Mandalay city. The investigated buildings vary from 12m-80 m in height, and mostly public residence structures. The predominant period obtained from frequency results of the investigated buildings were given by horizontal to vertical spectral ratio (HVSR) for each building. The fundamental period results have been calculated in the form of Fourier amplitude spectra of translation along with the main structure. Based on that, the height (H)-period(T) relationship was observed as T=0.012H-0.017H in the buildings of Yangon and, observed the relationship as T=0.014H-0.019H in the buildings of Mandalay. The results showed that the relationship between height and natural period was slightly under the relationship T=0.02H that is used for Japanese reinforced concrete buildings, which indicated that the results depend on the properties and characteristics of materials used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HVSR" title="HVSR">HVSR</a>, <a href="https://publications.waset.org/abstracts/search?q=height-period%20relationship" title=" height-period relationship"> height-period relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=microtremor" title=" microtremor"> microtremor</a>, <a href="https://publications.waset.org/abstracts/search?q=Myanmar%20earthquake" title=" Myanmar earthquake"> Myanmar earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20structures" title=" reinforced concrete structures"> reinforced concrete structures</a> </p> <a href="https://publications.waset.org/abstracts/110356/seismic-evaluation-of-reinforced-concrete-buildings-in-myanmar-based-on-microtremor-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110356.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4117</span> Optimization of Reinforced Concrete Buildings According to the Algerian Seismic Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nesreddine%20Djafar%20Henni">Nesreddine Djafar Henni</a>, <a href="https://publications.waset.org/abstracts/search?q=Nassim%20Djedoui"> Nassim Djedoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Chebili"> Rachid Chebili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent decades have witnessed significant efforts being made to optimize different types of structures and components. The concept of cost optimization in reinforced concrete structures, which aims at minimizing financial resources while ensuring maximum building safety, comprises multiple materials, and the objective function for their optimal design is derived from the construction cost of the steel as well as concrete that significantly contribute to the overall weight of reinforced concrete (RC) structures. To achieve this objective, this work has been devoted to optimizing the structural design of 3D RC frame buildings which integrates, for the first time, the Algerian regulations. Three different test examples were investigated to assess the efficiency of our work in optimizing RC frame buildings. The hybrid GWOPSO algorithm is used, and 30000 generations are made. The cost of the building is reduced by iteration each time. Concrete and reinforcement bars are used in the building cost. As a result, the cost of a reinforced concrete structure is reduced by 30% compared with the initial design. This result means that the 3D cost-design optimization of the framed structure is successfully achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=automation" title=" automation"> automation</a>, <a href="https://publications.waset.org/abstracts/search?q=API" title=" API"> API</a>, <a href="https://publications.waset.org/abstracts/search?q=Malab" title=" Malab"> Malab</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20structures" title=" RC structures"> RC structures</a> </p> <a href="https://publications.waset.org/abstracts/182542/optimization-of-reinforced-concrete-buildings-according-to-the-algerian-seismic-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182542.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">49</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4116</span> Impact of Slenderness Ratios on the Seismic Behavior of Reinforced Concrete Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Boj%C3%B3rquez">Juan Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=F.%20de%20Jes%C3%BAs%20Merino"> F. de Jesús Merino</a>, <a href="https://publications.waset.org/abstracts/search?q=Ed%C3%A9n%20Boj%C3%B3rquez"> Edén Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Llanez-Tizoc"> Mario Llanez-Tizoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Federico%20Valenzuela-Beltr%C3%A1n"> Federico Valenzuela-Beltrán</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20R.%20Flores"> Mario R.

In this research, the overstrength factor (Ω) of reinforced concrete (RC) buildings and the parameters of Ω in TEC-2016 draft version have been explored. For this aim, 48 RC buildings have been modeled according to the current seismic code TEC-2007 and Turkish Building Code-500-2000 criteria. After modelling step, nonlinear static pushover analyses have been applied to these buildings by using TEC-2007 Section 7. After the nonlinear pushover analyses, capacity curves (lateral load-lateral top displacement curves) have been plotted for 48 RC buildings. Using capacity curves, overstrength factors (Ω) have been derived for each building. The obtained overstrength factor (Ω) values have been compared with TEC-2016 values for related building types, and the results have been interpreted. According to the obtained values from the study, overstrength factor (Ω) given in TEC-2016 draft code is found quite suitable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20buildings" title="reinforced concrete buildings">reinforced concrete buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=overstrength%20factor" title=" overstrength factor"> overstrength factor</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20pushover%20analysis" title=" static pushover analysis"> static pushover analysis</a> </p> <a href="https://publications.waset.org/abstracts/57749/an-investigation-on-overstrength-factor-o-of-reinforced-concrete-buildings-in-turkish-earthquake-draft-code-tec-2016" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57749.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">356</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4113</span> Effect of Blast Loads on the Seismically Designed Reinforced Concrete Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jhuma%20Debnath">Jhuma Debnath</a>, <a href="https://publications.waset.org/abstracts/search?q=Hrishikesh%20Sharma"> Hrishikesh Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work done here in this paper is dedicated to studying the effect of high blast explosives over the seismically designed buildings. Buildings are seismically designed in SAP 2000 software to simulate seismic designs of buildings using response spectrum method. Later these buildings have been studied applying blast loads with the same amount of the blast explosives. This involved varying the standoff distances of the buildings from the blast explosion. The study found out that, for a seismically designed building, the minimum standoff distance is to be at least 120m from the place of explosion for an average blast explosive weight of 20kg TNT. This has shown that the building does not fail due to this huge explosive weight of TNT but resists immediate collapse of the building. The results also show that the adverse effect of the column failure due to blasting is reduced to 73.75% from 22.5% due to the increase of the standoff distance from the blast loads. The maximum affected locations due to the blast loads are also detected in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20loads" title="blast loads">blast loads</a>, <a href="https://publications.waset.org/abstracts/search?q=seismically%20designed%20buildings" title=" seismically designed buildings"> seismically designed buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=standoff%20distance" title=" standoff distance"> standoff distance</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20buildings" title=" reinforced concrete buildings"> reinforced concrete buildings</a> </p> <a href="https://publications.waset.org/abstracts/98209/effect-of-blast-loads-on-the-seismically-designed-reinforced-concrete-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98209.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">235</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4112</span> Effective Width of Reinforced Concrete U-Shaped Walls Due to Shear Lag Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ryan%20D.%20Hoult">Ryan D.

However, in reality, a shear flow would develop in non-rectangular sections, where the longitudinal strains in between the web and flanges of the element would lag behind those at the boundary ends. This phenomenon, known as shear lag, can significantly reduce the expected moment capacity of non-rectangular reinforced concrete walls. This study focuses on shear lag effects in reinforced concrete U-shaped walls, which are commonly used as lateral load resisting elements in reinforced concrete buildings. An extensive number of finite element modelling analyses are conducted to estimate the vertical strain distributions across the web and flanges of a U-shaped wall with different axial load ratios and longitudinal reinforcement detailing. The results show that shear lag effects are prominent and sometimes significant in U-shaped walls, particularly for the wall sections perpendicular to the direction of loading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20lag" title="shear lag">shear lag</a>, <a href="https://publications.waset.org/abstracts/search?q=walls" title=" walls"> walls</a>, <a href="https://publications.waset.org/abstracts/search?q=U-shaped" title=" U-shaped"> U-shaped</a>, <a href="https://publications.waset.org/abstracts/search?q=moment-curvature" title=" moment-curvature"> moment-curvature</a> </p> <a href="https://publications.waset.org/abstracts/92183/effective-width-of-reinforced-concrete-u-shaped-walls-due-to-shear-lag-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92183.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4111</span> Analytical Model for Columns in Existing Reinforced Concrete Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%20Seok%20Lee">Chang Seok Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Whan%20Han"> Sang Whan Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Girbo%20Ko"> Girbo Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Debbie%20Kim"> Debbie Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Existing reinforced concrete structures are designed and built without considering seismic loads. The columns in such buildings generally exhibit widely spaced transverse reinforcements without using seismic hooks. Due to the insufficient reinforcement details in columns, brittle shear failure is expected in columns that may cause pre-mature building collapse mechanism during earthquakes. In order to retrofit those columns, the accurate seismic behavior of the columns needs to be predicted with proper analytical models.

While current procedures for evaluating existing buildings are complicated, and there is no limitation between short, middle-high, and tall buildings. This research utilizes a simplified method for assessing structures, which is adequate for existing reinforced concrete buildings. To approach this aim, Simple Lateral Mechanisms Analysis (SLaMA) procedure proposed by NZSEE (New Zealand Society for Earthquake Engineering) has been carried out. In this study, three RC moment-resisting frame buildings are determined. First, these buildings have been evaluated by inelastic static procedure (Pushover) based on acceptance criteria. Then, Park-Ang Damage Index is determined for the whole members of each building by Inelastic Time History Analysis. Next, the Simple Lateral Mechanisms Analysis procedure, a hand method, is carried out to define the capacity of structures. Ultimately, existing procedures are compared with Peak Ground Acceleration caused to fail (PGAfail). The results of this comparison emphasize that the Pushover procedure and SLaMA method define a greater value of PGAfail than the Park-Ang Damage model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peak%20ground%20acceleration%20caused%20to%20fail" title="peak ground acceleration caused to fail">peak ground acceleration caused to fail</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20moment-frame%20buildings" title=" reinforced concrete moment-frame buildings"> reinforced concrete moment-frame buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20vulnerability%20analysis" title=" seismic vulnerability analysis"> seismic vulnerability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20lateral%20mechanisms%20analysis" title=" simple lateral mechanisms analysis"> simple lateral mechanisms analysis</a> </p> <a href="https://publications.waset.org/abstracts/165180/simplifying-seismic-vulnerability-analysis-for-existing-reinforced-concrete-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165180.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4109</span> Flexural Strength of Alkali Resistant Glass Textile Reinforced Concrete Beam with Prestressing </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jongho%20Park">Jongho Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Taekyun%20Kim"> Taekyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jungbhin%20You"> Jungbhin You</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungnam%20Hong"> Sungnam Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun-Kyu%20Park"> Sun-Kyu Park </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the aging of bridges, increasing of maintenance costs and decreasing of structural safety is occurred.

A textile reinforced concrete can reduce carbon emissions by reduced concrete and without steel bars, so a lot of structural behavior studies are needed.

Addition of RC shear wall as infill or external walls into the structural system has been a commonly preferred strengthening technique since the Big Erzincan Earthquake occurred in Turkey, 1992. The newly added rigid infill walls act primarily as shear walls and relieve the non-ductile existing frames from being subjected to large shear demands providing that new RC inner or external walls are adequately anchored to the existing weak RC frame. The performance of the RC shear walls-RC weak frame connections by steel anchor dowels depends on some parameters such as compressive strength of the existing RC frame concrete, diameter and embedment length of anchored rebar, type of rebar, yielding stress of bar, properties of used chemicals, position of the anchor bars in RC. In this study, application problems of the steel anchor dowels have been checked with some field studies such as tensile test. Two different RC buildings which will be strengthened were selected, and before strengthening, some tests have been performed in the existing RC buildings. According to the field observation and experimental studies, if the concrete compressive strength is lower than 10 MPa, the performance of the anchors is reduced by 70%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anchor%20dowel" title="anchor dowel">anchor dowel</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wall" title=" shear wall"> shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=frame" title=" frame"> frame</a> </p> <a href="https://publications.waset.org/abstracts/47308/application-problems-of-anchor-dowels-in-reinforced-concrete-shear-wall-and-frame-connections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47308.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4107</span> Prediction of Structural Response of Reinforced Concrete Buildings Using Artificial Intelligence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Boj%C3%B3rquez">Juan Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20E.%20Reyes"> Henry E.

In the past decades, fiber reinforced polymer (FRP) bars had been widely used to substitute the steel bars due to their high resistance to corrosion, high tensile capacity, and low weight in comparison with steel. Experimental studies on the behavior of FRP bar reinforced concrete beams had been carried out worldwide for a few decades. While the research on such structural members under elevated temperatures is still very limited. In this research, the flexural behavior of heat-damaged concrete beams reinforced with FRP bars is studied. Two types of FRP rebar namely, carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP), are used. The beams are subjected to four levels of temperature before tested to monitor their flexural behavior. The results are compared with other concrete beams reinforced with regular steel bars. The results show that the beams reinforced with CFRP bars and GFRP bars had higher flexural capacity than the beams reinforced with steel bars even if heated up to 400°C and 300°C, respectively. After that the beams reinforced with steel bars had the superiority. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20beams" title="concrete beams">concrete beams</a>, <a href="https://publications.waset.org/abstracts/search?q=FRP%20rebar" title=" FRP rebar"> FRP rebar</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20behavior" title=" flexural behavior"> flexural behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=heat-damaged" title=" heat-damaged"> heat-damaged</a> </p> <a href="https://publications.waset.org/abstracts/1470/flexural-behavior-of-heat-damaged-concrete-beams-reinforced-with-fiber-reinforced-polymer-frp-bars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1470.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4105</span> Evaluation of Prestressed Reinforced Concrete Slab Punching Shear Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhi%20Zhang">Zhi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Liling%20Cao"> Liling Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyedbabak%20Momenzadeh"> Seyedbabak Momenzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Davey"> Lisa Davey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reinforced concrete (RC) flat slab-column systems are commonly used in residential or office buildings, as the flat slab provides efficient clearance resulting in more stories at a given height than regular reinforced concrete beam-slab system. Punching shear of slab-column joints is a critical component of two-way reinforced concrete flat slab design. The unbalanced moment at the joint is transferred via slab moment and shear forces. ACI 318 provides an equation to evaluate the punching shear under the design load. It is important to note that the design code considers gravity and environmental load when considering the design load combinations, while it does not consider the effect from differential foundation settlement, which may be a governing load condition for the slab design. This paper describes how prestressed reinforced concrete slab punching shear is evaluated based on ACI 318 provisions and finite element analysis. A prestressed reinforced concrete slab under differential settlements is studied using the finite element modeling methodology. The punching shear check equation is explained. The methodology to extract data for punching shear check from the finite element model is described and correlated with the corresponding code provisions. The study indicates that the finite element analysis results should be carefully reviewed and processed in order to perform accurate punching shear evaluation. Conclusions are made based on the case studies to help engineers understand the punching shear behavior in prestressed and non-prestressed reinforced concrete slabs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=differential%20settlement" title="differential settlement">differential settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=prestressed%20reinforced%20concrete%20slab" title=" prestressed reinforced concrete slab"> prestressed reinforced concrete slab</a>, <a href="https://publications.waset.org/abstracts/search?q=punching%20shear" title=" punching shear"> punching shear</a> </p> <a href="https://publications.waset.org/abstracts/110344/evaluation-of-prestressed-reinforced-concrete-slab-punching-shear-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110344.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4104</span> Experimental Analysis of Composite Timber-Concrete Beam with CFRP Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Vlcek">O.

The results of analyses showed that the use of reinforced masonry infill panels in RC frame structures can have beneficial effects on structural performance. It was confirmed that the use of masonry infill panels results in an increment in strength and stiffness of the framed buildings, followed by a reduction in displacement demand for the structural systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reinforced%20masonry%20infill%20panels" title="reinforced masonry infill panels">reinforced masonry infill panels</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20static%20analysis" title=" nonlinear static analysis"> nonlinear static analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=incremental%20dynamic%20analysis" title=" incremental dynamic analysis"> incremental dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=low-rise%20reinforced%20concrete%20frames" title=" low-rise reinforced concrete frames"> low-rise reinforced concrete frames</a>, <a href="https://publications.waset.org/abstracts/search?q=mid-rise%20reinforced%20concrete%20frames" title=" mid-rise reinforced concrete frames"> mid-rise reinforced concrete frames</a> </p> <a href="https://publications.waset.org/abstracts/14413/the-effect-of-masonry-infills-on-the-seismic-response-of-reinforced-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4101</span> Mechanical Properties of Fibre Reinforced High Performance Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Dembovska">Laura Dembovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Diana%20Bajare"> Diana Bajare</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitalijs%20Lusis"> Vitalijs Lusis</a>, <a href="https://publications.waset.org/abstracts/search?q=Genadijs%20Sahmenko"> Genadijs Sahmenko</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksandrs%20Korjakins"> Aleksandrs Korjakins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focused on the mechanical properties of the fibre reinforced High Performance Concrete. The most important benefits of addition of fibres to the concrete mix are the hindrance of the development of microcracks, the delay of the propagation of microcracks to macroscopic cracks and the better ductility after microcracks have been occurred. This work presents an extensive comparative experimental study on six different types of fibres (alkali resistant glass, polyvinyl alcohol fibres, polypropylene fibres and carbon fibres) with the same binding High Performance Concrete matrix. The purpose was to assess the influence of the type of fibre on the mechanical properties of Fibre Reinforced High Performance Concrete. Therefore, in this study three main objectives have been chosen: 1) analyze the structure of the bulk cementitious matrix, 2) determine the influence of fibres and distribution in the matrix on the mechanical properties of fibre reinforced High Performance Concrete and 3) characterize the microstructure of the fibre-matrix interface.

Also, due to the abnormal climate phenomenon, cracking of reinforced concrete structures is accelerated. Therefore, research on the Textile Reinforced Concrete (TRC) which replaced reinforcement with textile is under study. However, in previous studies, adhesion performance to single yarn was examined without parameters, which does not reflect the effect of fiber twisting and concrete strength. In the present paper, the effect of concrete strength and embedded length on 2400tex (gram per 1000 meters) and 640tex textile were investigated. The result confirm that the increasing compressive strength of the concrete did not affect the pullout strength. However, as the embedded length increased, the pullout strength tended to increase gradually, especially at 2400tex with more twists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=textile" title="textile">textile</a>, <a href="https://publications.waset.org/abstracts/search?q=TRC" title=" TRC"> TRC</a>, <a href="https://publications.waset.org/abstracts/search?q=pullout" title=" pullout"> pullout</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20length" title=" embedded length"> embedded length</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a> </p> <a href="https://publications.waset.org/abstracts/67482/pullout-strength-of-textile-reinforcement-in-concrete-by-embedded-length-and-concrete-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67482.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4099</span> Studying the Bond Strength of Geo-Polymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rama%20Seshu%20Doguparti">Rama Seshu Doguparti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the experimental investigation on the bond behavior of geo polymer concrete.

Furthermore, there exist a large number of buildings that need retrofitting of the joints before the next earthquake. The paper reports the results of the experimental programme, constituted of three beam-column reinforced concrete joints at a scale of one to three (1/3) tested under the effect of a pre-stressing axial load acting over the column. The beams were subjected at their ends to an alternate cyclic loading under displacement control to simulate a seismic action. Strain and cracking fields were monitored with the help a digital recording camera. Following the analysis of the results, a comparison can be made between the performances in terms of ductility, strength, and mode of failure of the different strengthening solution considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fibre%20reinforced%20polymers" title="fibre reinforced polymers">fibre reinforced polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=joints" title=" joints"> joints</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=beam%20columns" title=" beam columns"> beam columns</a> </p> <a href="https://publications.waset.org/abstracts/16721/seismic-strengthening-of-reinforced-concrete-beam-column-joint-by-reversible-mixed-technologies-of-frp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16721.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">440</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4097</span> Seismic Behavior and Loss Assessment of High–Rise Buildings with Light Gauge Steel–Concrete Hybrid Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bing%20Lu">Bing Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuang%20Li"> Shuang Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongyuan%20Zhou"> Hongyuan Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The steel–concrete hybrid structure has been extensively employed in high–rise buildings and super high–rise buildings. The light gauge steel–concrete hybrid structure, including light gauge steel structure and concrete hybrid structure, is a new–type steel–concrete hybrid structure, which possesses some advantages of light gauge steel structure and concrete hybrid structure. The seismic behavior and loss assessment of three high–rise buildings with three different concrete hybrid structures were investigated through finite element software, respectively. The three concrete hybrid structures are reinforced concrete column–steel beam (RC‒S) hybrid structure, concrete–filled steel tube column–steel beam (CFST‒S) hybrid structure, and tubed concrete column–steel beam (TC‒S) hybrid structure. The nonlinear time-history analysis of three high–rise buildings under 80 earthquakes was carried out. After simulation, it indicated that the seismic performances of three high–rise buildings were superior. Under extremely rare earthquakes, the maximum inter–storey drifts of three high–rise buildings are significantly lower than 1/50. The inter–storey drift and floor acceleration of high–rise building with CFST‒S hybrid structure were bigger than those of high–rise buildings with RC‒S hybrid structure, and smaller than those of high–rise building with TC‒S hybrid structure. Then, based on the time–history analysis results, the post-earthquake repair cost ratio and repair time of three high–rise buildings were predicted through an economic performance analysis method proposed in FEMA‒P58 report. Under frequent earthquakes, basic earthquakes and rare earthquakes, the repair cost ratio and repair time of three high-rise buildings were less than 5% and 15 days, respectively. Under extremely rare earthquakes, the repair cost ratio and repair time of high-rise buildings with TC‒S hybrid structure were the most among three high rise buildings. Due to the advantages of CFST-S hybrid structure, it could be extensively employed in high-rise buildings subjected to earthquake excitations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20behavior" title="seismic behavior">seismic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20assessment" title=" loss assessment"> loss assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20gauge%20steel%E2%80%93concrete%20hybrid%20structure" title=" light gauge steel–concrete hybrid structure"> light gauge steel–concrete hybrid structure</a>, <a href="https://publications.waset.org/abstracts/search?q=high%E2%80%93rise%20building" title=" high–rise building"> high–rise building</a>, <a href="https://publications.waset.org/abstracts/search?q=time%E2%80%93history%20analysis" title=" time–history analysis"> time–history analysis</a> </p> <a href="https://publications.waset.org/abstracts/133887/seismic-behavior-and-loss-assessment-of-high-rise-buildings-with-light-gauge-steel-concrete-hybrid-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133887.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">185</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4096</span> Impact of Natural Period and Epicentral Distance on Storey Lateral Displacements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saida%20Dorbani">Saida Dorbani</a>, <a href="https://publications.waset.org/abstracts/search?q=M%27hammed%20Badaoui"> M'hammed Badaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Djilali%20Benouar"> Djilali Benouar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the effect of the building design and epicentral distance on the storey lateral displacement, for several reinforced concrete buildings (6, 9 and 12 stories), with three floor plans: symmetric, mono symmetric, and unsymmetrical.

During this period, we have constructed many structures like buildings, bridges, industrial structures, pavement, water tanks etc. using this construction material. These structures have been created with huge investment of resources. It is essential to maintain those structures in functional condition. Since deterioration in RCC Structures is a common and natural phenomenon it is required to have a detailed plan, methodology for structural repair and rehabilitation shall be in place for dealing such issues. It is important to know exact reason of distress, type of distress and correct method of repair concrete structures. The different methods of repair are described in paper according to distress category which can be refereed for repair. Major finding of the study is that to protect our structure we need to have maintenance frequency and correct material to be chosen for repair. Also workmanship during repair needs to be taken utmost care for quality repair. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deterioration" title="deterioration">deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20condition" title=" functional condition"> functional condition</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20cement%20concrete" title=" reinforced cement concrete"> reinforced cement concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a> </p> <a href="https://publications.waset.org/abstracts/41322/structural-rehabilitation-retrofitting-and-strengthening-of-reinforced-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4094</span> Cyclic Loading Tests of Reinforced Concrete Frame Structures Strengthened by Externally-Anchored Precast Wall-Panel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung-Ho%20Choi">Seung-Ho Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Yuel%20Oh"> Jae Yuel Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%20Sung%20Lim"> Chi Sung Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ho%20Seong%20Jung"> Ho Seong Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang%20Su%20Kim"> Kang Su Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, various strengthening methods for buildings have been developed, but most of them require quite a long construction period during which the building users need to be patient on uncomfortable working environments including various lousy noises or even evacuation of the buildings. In this study, externally anchored precast wall-panel method (EPCW) for strengthening non-seismic reinforced concrete (RC) structures has been proposed, which is occupant-friendly technique because the strengthening walls are manufactured at factory and can be tightened to the members very quickly at the site. In order to investigate the structural performance of the specimens strengthened by the EPCW method, a total of four specimens were fabricated, and tested under axial and reversed cyclic lateral loads. The test results showed that the lateral resistances of the specimens strengthened by the EPCW method were greatly enhanced in both positive and negative directions, compared to the RC specimen having non-seismic details. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=precast%20wall" title="precast wall">precast wall</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20strengthening" title=" seismic strengthening"> seismic strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=externally-anchored" title=" externally-anchored"> externally-anchored</a> </p> <a href="https://publications.waset.org/abstracts/75858/cyclic-loading-tests-of-reinforced-concrete-frame-structures-strengthened-by-externally-anchored-precast-wall-panel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75858.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4093</span> Optimal Load Factors for Seismic Design of Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Boj%C3%B3rquez">Juan Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20E.%20Ruiz"> Sonia E.

The expected cost of damage from future earthquakes within the life of the structure is estimated, and realistic cost functions are assumed. The functions include: Repair cost, cost of contents damage, cost associated with loss of life, cost of injuries and economic loss. The loads considered are dead, live and earthquake load. The study is performed for reinforced concrete buildings located in Mexico City. The buildings are modeled as multiple-degree-of-freedom frame structures. The parameter selected to measure the structural damage is the maximum inter-story drift. The structural models are subjected to 31 soft-soil ground motions recorded in the Lake Zone of Mexico City. In order to obtain the annual structural failure rates, a numerical integration method is applied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=load%20factors" title="load factors">load factors</a>, <a href="https://publications.waset.org/abstracts/search?q=life-cycle%20analysis" title=" life-cycle analysis"> life-cycle analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20design" title=" seismic design"> seismic design</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20buildings" title=" reinforced concrete buildings"> reinforced concrete buildings</a> </p> <a href="https://publications.waset.org/abstracts/22167/optimal-load-factors-for-seismic-design-of-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22167.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">617</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4092</span> Layered Fiberconcrete Element Building Technology and Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vitalijs%20Lusis">Vitalijs Lusis</a>, <a href="https://publications.waset.org/abstracts/search?q=Videvuds-Arijs%20Lapsa"> Videvuds-Arijs Lapsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Kononova"> Olga Kononova</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrejs%20Krasnikovs"> Andrejs Krasnikovs </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Steel fibres use in a concrete, such way obtaining Steel Fibre Reinforced Concrete (SFRC), is an important technological direction in building industry. Steel fibers are substituting the steel bars in conventional concrete in another situation is possible to combine them in the concrete structures. Traditionally fibers are homogeneously dispersed in a concrete. At the same time in many situations fiber concrete with homogeneously dispersed fibers is not optimal (majority of added fibers are not participating in a load bearing process). It is obvious, that is possible to create constructions with oriented fibers distribution in them, in different ways. Present research is devoted to one of them.
