Mbako</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The failure of material usually involves elastoplastic deformation and fracturing. Continuum mechanics can effectively deal with plastic deformation by using a yield function and the flow rule. At the same time, it has some limitations in dealing with the fracture problem since it is a theory based on the continuous field hypothesis. The lattice model can simulate the fracture problem very well, but it is inadequate for dealing with plastic deformation. Based on the discretized virtual internal bond model (DVIB), this paper proposes a lattice model that can account for plasticity. DVIB is a lattice method that considers material to comprise bond cells. Each bond cell may have any geometry with a finite number of bonds. The two-body or multi-body potential can characterize the strain energy of a bond cell. The two-body potential leads to the fixed Poisson ratio, while the multi-body potential can overcome the limitation of the fixed Poisson ratio. In the present paper, the modified Stillinger-Weber (SW), a multi-body potential, is employed to characterize the bond cell energy. The SW potential is composed of two parts. One part is the two-body potential that describes the interatomic interactions between particles. Another is the three-body potential that represents the bond angle interactions between particles. Because the SW interaction can represent the bond stretch and bond angle contribution, the SW potential-based DVIB (SW-DVIB) can represent the various Poisson ratios. To embed the plasticity in the SW-DVIB, the plasticity is considered in the two-body part of the SW potential. It is done by reducing the bond stiffness to a lower level once the bond reaches the yielding point. While before the bond reaches the yielding point, the bond is elastic. When the bond deformation exceeds the yielding point, the bond stiffness is softened to a lower value. When unloaded, irreversible deformation occurs. With the bond length increasing to a critical value, termed the failure bond length, the bond fails. The critical failure bond length is related to the cell size and the macro fracture energy. By this means, the fracture energy is conserved so that the cell size sensitivity problem is relieved to a great extent. In addition, the plasticity and the fracture are also unified at the bond level. To make the DVIB able to simulate different Poisson ratios, the three-body part of the SW potential is kept elasto-brittle. The bond angle can bear the moment before the bond angle increment is smaller than a critical value. By this method, the SW-DVIB can simulate the plastic deformation and the fracturing process of material with various Poisson ratios. The elastoplastic SW-DVIB is used to simulate the plastic deformation of a material, the plastic fracturing process, and the tunnel plastic deformation. It has been shown that the current SW-DVIB method is straightforward in simulating both elastoplastic deformation and plastic fracture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lattice%20model" title="lattice model">lattice model</a>, <a href="https://publications.waset.org/abstracts/search?q=discretized%20virtual%20internal%20bond" title=" discretized virtual internal bond"> discretized virtual internal bond</a>, <a href="https://publications.waset.org/abstracts/search?q=elastoplastic%20deformation" title=" elastoplastic deformation"> elastoplastic deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20stillinger-weber%20potential" title=" modified stillinger-weber potential"> modified stillinger-weber potential</a> </p> <a href="https://publications.waset.org/abstracts/157163/elastoplastic-modified-stillinger-weber-potential-based-discretized-virtual-internal-bond-and-its-application-to-the-dynamic-fracture-propagation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157163.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">98</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">4256</span> Research of Interaction between Layers of Compressed Composite Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daumantas%20Zidanavicius">Daumantas Zidanavicius</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to investigate the bond between concrete and steel in the circular steel tube column filled with concrete, the 7 series of specimens were tested with the same geometrical parameters but different concrete properties.

And for the second type, mechanical components were used. All 7 series of the short columns were modeled by FEM and tested experimentally. In the work, big attention was taken to the bond-slip models between steel and concrete. Results show that additives to concrete let increase the bond strength up to two times and the mechanical anchorage –up to 6 times compared to control specimens without additives and anchorage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20filled%20steel%20tube" title="concrete filled steel tube">concrete filled steel tube</a>, <a href="https://publications.waset.org/abstracts/search?q=push-out%20test" title=" push-out test"> push-out test</a>, <a href="https://publications.waset.org/abstracts/search?q=bond%20slip%20relationship" title=" bond slip relationship"> bond slip relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=bond%20stress%20distribution" title=" bond stress distribution"> bond stress distribution</a> </p> <a href="https://publications.waset.org/abstracts/133631/research-of-interaction-between-layers-of-compressed-composite-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133631.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">124</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">4255</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.

This study investigates the influence of bond thickness on the behaviour of interface, failure mode, and bond strength of externally bonded FRP-to-timber interface. In the present study, 106 single shear joint specimens have been investigated. Experiment results showed that higher layers of FRP increase the ultimate load carrying capacity of interface; conversely, such increase led to decrease the slip of interface. Moreover, samples with more layers of FRPs may fail in a brittle manner without noticeable warning that collapse is imminent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fibre%20reinforced%20polymer" title="fibre reinforced polymer">fibre reinforced polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=FRP" title=" FRP"> FRP</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20shear%20test" title=" single shear test"> single shear test</a>, <a href="https://publications.waset.org/abstracts/search?q=bond%20thickness" title=" bond thickness"> bond thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=bond%20strength" title=" bond strength"> bond strength</a> </p> <a href="https://publications.waset.org/abstracts/100515/experimental-investigation-on-the-effect-of-bond-thickness-on-the-interface-behaviour-of-fibre-reinforced-polymer-sheet-bonded-to-timber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100515.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">229</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">4253</span> Model-Independent Price Bounds for the Swiss Re Mortality Bond 2003</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumari%20Bahl">Raj Kumari Bahl</a>, <a href="https://publications.waset.org/abstracts/search?q=Sotirios%20Sabanis"> Sotirios Sabanis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we are concerned with the valuation of the first Catastrophic Mortality Bond that was launched in the market namely the Swiss Re Mortality Bond 2003. This bond encapsulates the behavior of a well-defined mortality index to generate payoffs for the bondholders. Pricing this bond is a challenging task. We adapt the payoff of the terminal principal of the bond in terms of the payoff of an Asian put option and present an approach to derive model-independent bounds exploiting comonotonic theory. We invoke Jensen’s inequality for the computation of lower bounds and employ Lagrange optimization technique to achieve the upper bound. The success of these bounds is based on the availability of compatible European mortality options in the market. We carry out Monte Carlo simulations to estimate the bond price and illustrate the strength of these bounds across a variety of models. The fact that our bounds are model-independent is a crucial breakthrough in the pricing of catastrophic mortality bonds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mortality%20bond" title="mortality bond">mortality bond</a>, <a href="https://publications.waset.org/abstracts/search?q=Swiss%20Re%20Bond" title=" Swiss Re Bond"> Swiss Re Bond</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality%20index" title=" mortality index"> mortality index</a>, <a href="https://publications.waset.org/abstracts/search?q=comonotonicity" title=" comonotonicity"> comonotonicity</a> </p> <a href="https://publications.waset.org/abstracts/54923/model-independent-price-bounds-for-the-swiss-re-mortality-bond-2003" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54923.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">250</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">4252</span> An Experimental Investigation of Bond Properties of Reinforcements Embedded in Geopolymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jee-Sang%20Kim">Jee-Sang Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Ho%20Park"> Jong Ho Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Geopolymer concretes are a new class of construction materials that have emerged as an alternative to Ordinary Portland cement concrete. Considerable researches have been carried out on material development of geopolymer concrete, however, a few studies have been reported on the structural use of them. This paper presents the bond behaviors of reinforcement embedded in fly ash based geopolymer concrete. The development lengths of reinforcement for various compressive strengths of concrete, 20, 30 and 40 MPa, and reinforcement diameters, 10, 16, and 25 mm are investigated. Total 27 specimens were manufactured and pull-out test according to EN 10080 was applied to measure bond strength and slips between concrete and reinforcements. The average bond strengths decreased from 23.06MPa to 17.26 MPa, as the diameters of reinforcements increased from 10mm to 25mm. The compressive strength levels of geopolymer concrete showed no significant influence on bond strengths in this study. Also, the bond-slip relations between geopolymer concrete and reinforcement are derived using non-linear regression analysis for various experimental conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond-slip%20relation" title="bond-slip relation">bond-slip relation</a>, <a href="https://publications.waset.org/abstracts/search?q=bond%20strength" title=" bond strength"> bond strength</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer%20concrete" title=" geopolymer concrete"> geopolymer concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=pull-out%20test" title=" pull-out test"> pull-out test</a> </p> <a href="https://publications.waset.org/abstracts/14860/an-experimental-investigation-of-bond-properties-of-reinforcements-embedded-in-geopolymer-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14860.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">349</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">4251</span> Managing Virtual Teams in a Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Jafari%20Toosy">M.

Top coat and bond coat compose the TBC and top coat consists of a ceramic and bond coat increases adhesion between the top coat and the substrate. The TBC technology drops the substrate surface temperature by about 150~200°C. In addition, the TBC system has a cooling system to lower the blade temperature by the air flow inside the blade. Then, as a result, the thermal gradient occurs inside the blade by cooling. Also, the internal stress occurs due to the difference in thermal expansion. In this paper, the finite element analyses (FEA) were performed and stress changes were derived according to the thermal gradient of the TBC system. The stress was increased due to the cooling, but difference of the stress between the top coat and bond coat was decreased. So, delamination in the interface between top coat and bond coat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine%20blade" title="gas turbine blade">gas turbine blade</a>, <a href="https://publications.waset.org/abstracts/search?q=Thermal%20Barrier%20Coating%20%28TBC%29" title=" Thermal Barrier Coating (TBC)"> Thermal Barrier Coating (TBC)</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20gradient" title=" thermal gradient"> thermal gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=Finite%20Element%20Analysis%20%28FEA%29" title=" Finite Element Analysis (FEA)"> Finite Element Analysis (FEA)</a> </p> <a href="https://publications.waset.org/abstracts/15385/evaluation-of-thermal-barrier-coating-applied-to-the-gas-turbine-blade-according-to-the-thermal-gradient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15385.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">607</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">4248</span> A Study on the Improvement of the Bond Performance of Polypropylene Macro Fiber according to Longitudinal Shape Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-yong%20Choi">Sung-yong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Woo-tai%20Jung"> Woo-tai Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-hwan%20Park"> Young-hwan Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study intends to improve the bond performance of the polypropylene fiber used as reinforcing fiber for concrete by changing its shape into double crimped type through the enhancement its fabrication process.

For each isomeric pair we calculated: H-bond energy (ΔEB…H), charge-transfer (QCT), where B is atom bearing lone-pairs in CO, CNH, NCH, N2O, and NHCO, H-bond distances (RB…H), the elongation of HF bond (ΔRHF) and the red-shift of HF stretching frequency (ΔVHF). We conclude that the principle difference in the relative stability between each isomeric pair is attributed to distinctive interaction of carbon and oxygen lone pairs of CO, carbon and nitrogen lone-pairs of CNH and NCH, and nitrogen and oxygen lone pairs of N2O and NHCO into the unfilled antibond on HF (σ*HF). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charge%20transfer" title="charge transfer">charge transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20chemistry" title=" computational chemistry"> computational chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=isomeric%20hydrogen%20bond" title=" isomeric hydrogen bond"> isomeric hydrogen bond</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20bond%20orbital" title=" natural bond orbital "> natural bond orbital </a> </p> <a href="https://publications.waset.org/abstracts/37558/investigating-the-difference-in-stability-of-various-isomeric-hydrogen-bonded-dimers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37558.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">246</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">4245</span> Emerging Virtual Linguistic Landscape Created by Members of Language Community in TikTok</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kai%20Zhu">Kai Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shanhua%20He"> Shanhua He</a>, <a href="https://publications.waset.org/abstracts/search?q=Yujiao%20Chang"> Yujiao Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the virtual linguistic landscape of an emerging virtual language community in TikTok, a language community realizing immediate and non-immediate communication without a precise Spatio-temporal domain or a specific socio-cultural boundary or interpersonal network.

Propaganda tries to get the message across to people or masses to effect rather than to provide objective information. There are many types of propaganda. Especially, political propaganda is a very powerful method that is used by states during in both war and peace. The aim of this method is to create a reaction against them by showing within the framework of internal and external enemies. Propaganda can be practiced by many different methods. Especially during the Cold War Era, the US and USSR have tried to create an ideological effect by using the mass media intensively. Cinema, which is located at the beginning of these methods, is the most powerful weapon to influence the masses. In this study, the historical process of the Cold War is examined. Especially, these propagandas that had been used by United States and The Soviet Union were investigated. The purposes of propaganda and construction methods were presented. Cold War events and relations between the US and the USSR during the Cold War will be discussed. Outlooks of two countries to each other during the Cold War, propaganda techniques used defectively during Cold War and how to use the cinema as a propaganda tool will be examined. The film "From Russia with Love, James Bond 007" that was filmed in Cold War were examined to explain how cinema was used as a propaganda tool in this context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cinema" title="cinema">cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20war" title=" cold war"> cold war</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Bond" title=" James Bond"> James Bond</a>, <a href="https://publications.waset.org/abstracts/search?q=propaganda" title=" propaganda"> propaganda</a> </p> <a href="https://publications.waset.org/abstracts/7256/hot-face-of-cold-war-007-james-bond" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7256.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">519</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">4242</span> Push-Out Bond Strength of Two Root-End Filling Materials in Root-End Cavities Prepared by Er,Cr: YSGG Laser or Ultrasonic Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noushin%20Shokouhinejad">Noushin Shokouhinejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Razmi"> Hasan Razmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Fekrazad"> Reza Fekrazad</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Asgary"> Saeed Asgary</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Neshati"> Ammar Neshati</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Assadian"> Hadi Assadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanam%20Kheirieh"> Sanam Kheirieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study compared the push-out bond strength of mineral trioxide aggregate (MTA) and a new endodontic cement (NEC) as root-end filling materials in root-end cavities prepared by ultrasonic technique (US) or Er,Cr:YSGG laser (L). Eighty single-rooted extracted human teeth were endodontically treated, apicectomised and randomly divided into four following groups (n = 20): US/MTA, US/NEC, L/MTA and L/NEC. In US/MTA and US/NEC groups, rooted cavities were prepared with ultrasonic retrotip and filled with MTA and NEC, respectively. In L/MTA and L/NEC groups, root-end cavities were prepared using Er, Cr:YSGG laser and filled with MTA and NEC, respectively. Each root was cut apically to create a 2 mm-thick root slice for measurement of bond strength using a universal testing machine. Then, all slices were examined to determine the mode of bond failure. Data were analysed using two-way ANOVA. Root-end filling materials showed significantly higher bond strength in root-end cavities prepared using the ultrasonic technique (US/MTA and US/NEC) (P < 0.001). The bond strengths of MTA and NEC did not differ significantly. The failure modes were mainly adhesive for MTA, but cohesive for NEC. In conclusion, bond strengths of MTA and NEC to root-end cavities were comparable and higher in ultrasonically prepared cavities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20strength" title="bond strength">bond strength</a>, <a href="https://publications.waset.org/abstracts/search?q=Er" title=" Er"> Er</a>, <a href="https://publications.waset.org/abstracts/search?q=Cr%3AYSGG%20laser" title="Cr:YSGG laser">Cr:YSGG laser</a>, <a href="https://publications.waset.org/abstracts/search?q=MTA" title=" MTA"> MTA</a>, <a href="https://publications.waset.org/abstracts/search?q=NEC" title=" NEC"> NEC</a>, <a href="https://publications.waset.org/abstracts/search?q=root-end%20cavity" title=" root-end cavity"> root-end cavity</a> </p> <a href="https://publications.waset.org/abstracts/17770/push-out-bond-strength-of-two-root-end-filling-materials-in-root-end-cavities-prepared-by-ercr-ysgg-laser-or-ultrasonic-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17770.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">345</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">4241</span> Effect of Impact Load on the Bond between Steel and CFRP Laminate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Al-Mosawe">Alaa Al-Mosawe</a>, <a href="https://publications.waset.org/abstracts/search?q=Riadh%20Al-Mahaidi"> Riadh Al-Mahaidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon fiber reinforced polymers have been wildly used to strengthen steel structural elements.

A number of researches have been focused on the bond characteristics of CFRP sheets to steel members under static, dynamic and fatigue loadings. There is a lack in understanding the behavior of the CFRP laminates under impact loading. This paper is showing the effect of high load rate on this bond. CFRP laminate CFK 150/2000 was used to strengthen steel joint by using Araldite 420 epoxy.

Long embedment was investigated as well to gain insights on the distribution of strain, slip, bar stress and bond stress along the bar especially in post-yield range. A total of 12 specimens were tested, by means of pull-out of the reinforcing bars from concrete blocks. It was found that the enhancement of local bond strength can be reached up to 50% and ductility of the bond behavior was improved significantly if HPFRCC is used. Also, under a constant strain at loaded end, HPFRCC has delayed yielding of bars at other location from the loaded end. Hence, the reduction of bond stress was slower for HPFRCC in comparison with NC. Due to the same reason, the total slips at loaded end for HPFRCC was smaller than NC as expected. Test results indicated that HPFRCC has better bond slip behavior which makes it a suitable material to be employed in anchorage zone such as beam-column joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20stress" title="bond stress">bond stress</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20performance%20fiber%20reinforced%20cement%20composites" title=" high performance fiber reinforced cement composites"> high performance fiber reinforced cement composites</a>, <a href="https://publications.waset.org/abstracts/search?q=slip" title=" slip"> slip</a>, <a href="https://publications.waset.org/abstracts/search?q=strain" title=" strain"> strain</a> </p> <a href="https://publications.waset.org/abstracts/29290/bond-slip-response-of-reinforcing-bars-embedded-in-high-performance-fiber-reinforced-cement-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29290.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">495</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">4238</span> Effect of Concrete Strength on the Bond Between Carbon Fiber Reinforced Polymer and Concrete in Hot Weather</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Usama%20Mohamed%20Ahamed">Usama Mohamed Ahamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research deals with the bond behavior of carbon FRP composite wraps adhered/bonded to the surface of the concrete. Four concrete mixes were designed to achieve a concrete compressive strength of 18, 22.5,25 and 30 MP after 28 days of curing. The focus of the study is on bond degradation when the hybrid structure is exposed to hot weather conditions. Specimens were exposed to 50 0C temperature duration 6 months and other specimens were sustained in laboratory temperature ( 20-24) 0C. Upon removing the specimens from their conditioning environment, tension tests were performed in the machine using a specially manufactured concrete cube holder. A lightweight mortar layer is used to protect the bonded carbon FRP layer on the concrete surface. The results show that the higher the concrete's compressive, the higher the bond strength. The high temperature decreases the bond strength between concrete and carbon fiber-reinforced polymer. The use of a protection layer is essential for concrete exposed to hot weather. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=bond" title=" bond"> bond</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20weather%20and%20carbon%20fiber" title=" hot weather and carbon fiber"> hot weather and carbon fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20fiber%20reinforced%20polymers" title=" carbon fiber reinforced polymers"> carbon fiber reinforced polymers</a> </p> <a href="https://publications.waset.org/abstracts/169015/effect-of-concrete-strength-on-the-bond-between-carbon-fiber-reinforced-polymer-and-concrete-in-hot-weather" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169015.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">107</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">4237</span> Virtual Reality Design Platform to Easily Create Virtual Reality Experiences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Casteleiro-%20Pitrez">J.

The dress was also sawn after which garment fit differences of real and virtual dress was researched. Four respondents whose figures were similar were used to evaluate the ease and strain deformations of the real and virtual dress. The scores that were given by the respondents wearing the real dress were compared to the ease and strain results that were given by the software. The main result was that respondents feel similar to the virtual stretch deformations but their ease feeling is not always matching the virtual ones.

Both as a stand-alone model or as a supplement to sustain competitive advantage for normal business models, building virtual communities has been hailed as one of the major strategic innovations of the new economy. However for a virtual community to evolve, the biggest challenge is how to make members actively give information or provide advice. Even in busy virtual communities, usually, only a small fraction of members post information actively. In order to investigate the determinants of information giving willingness of those contributors who usually actively provide their opinions, we proposed a model to understand the reasons for contribution in communities.

In addition, a plain concrete (without fiber) was produced and used as a control. Test results obtained showed that the steel fiber reinforced concrete (SFRC) had the highest compressive strength, modulus of rapture and bond stress values at room temperatures, the residual bond, flexural and compressive strengths of both FRC and plain concrete dropped sharply after exposure to high temperatures. The results also indicated that the reduction of bond, flexural and compressive strengths with increasing the exposed temperature was relatively less for SFRC than for plain, and FRC with PPF and PVA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20stress" title="bond stress">bond stress</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=elevated%20temperatures" title=" elevated temperatures"> elevated temperatures</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20reinforced%20concrete" title=" fiber reinforced concrete"> fiber reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rapture" title=" modulus of rapture"> modulus of rapture</a> </p> <a href="https://publications.waset.org/abstracts/29676/effect-of-fiber-types-and-elevated-temperatures-on-the-bond-characteristic-of-fiber-reinforced-concretes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29676.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">422</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">4228</span> Empirical Analytical Modelling of Average Bond Stress and Anchorage of Tensile Bars in Reinforced Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maruful%20H.%20Mazumder">Maruful H.

The normalized average bond stresses for the different variations of anchorage lengths are assessed according to the general form of a typical empirical analytical model of bond and anchorage.
