class="card-text"><strong>Abstract:</strong></p> <p>Structural design and analysis is an important and time-consuming process, particularly at the conceptual design stage. Decisions made at this stage can have an enormous effect on the entire project, as it becomes ever costlier and more difficult to alter the choices made early on in the construction process. Hence, optimisation of the early stages of structural design can provide important efficiencies in terms of cost and time. This paper suggests a structural design optimisation (SDO) framework in which Genetic Algorithms (GAs) may be used to semi-automate the production and optimisation of early structural design alternatives. This framework has the potential to leverage conceptual structural design innovation in Architecture, Engineering and Construction (AEC) projects. Moreover, this framework improves the collaboration between the architectural stage and the structural stage. It will be shown that this SDO framework can make this achievable by generating the structural model based on the extracted data from the architectural model. At the moment, the proposed SDO framework is in the process of validation, involving the distribution of an online questionnaire among structural engineers in the UK.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Building%20Information%20Modelling" title="Building Information Modelling">Building Information Modelling</a>, <a href="https://publications.waset.org/search?q=BIM" title=" BIM"> BIM</a>, <a href="https://publications.waset.org/search?q=Genetic%20Algorithm" title=" Genetic Algorithm"> Genetic Algorithm</a>, <a href="https://publications.waset.org/search?q=GA" title=" GA"> GA</a>, <a href="https://publications.waset.org/search?q=architecture-engineering-construction" title=" architecture-engineering-construction"> architecture-engineering-construction</a>, <a href="https://publications.waset.org/search?q=AEC" title=" AEC"> AEC</a>, <a href="https://publications.waset.org/search?q=Optimisation" title=" Optimisation"> Optimisation</a>, <a href="https://publications.waset.org/search?q=structure" title=" structure"> structure</a>, <a href="https://publications.waset.org/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/search?q=population" title=" population"> population</a>, <a href="https://publications.waset.org/search?q=generation" title=" generation"> generation</a>, <a href="https://publications.waset.org/search?q=selection" title=" selection"> selection</a>, <a href="https://publications.waset.org/search?q=mutation" title=" mutation"> mutation</a>, <a href="https://publications.waset.org/search?q=crossover" title=" crossover"> crossover</a>, <a href="https://publications.waset.org/search?q=offspring." title=" offspring.

As the innovative methodological development is evolving alongside computer sciences on one hand, researches are likely to confront more complex and larger water resources systems due to new challenges regarding increased water demands, climate change and human interventions, socio-economic concerns, and environment protection and sustainability. In this research, an automatic calibration scheme has been applied on the Gilan’s large-scale water resource model using mathematical programming. The water resource model’s calibration is developed in order to attune unknown water return flows from demand sites in the complex Sefidroud irrigation network and other related areas. The calibration procedure is validated by comparing several gauged river outflows from the system in the past with model results. The calibration results are pleasantly reasonable presenting a rational insight of the system. Subsequently, the unknown optimized parameters were used in a basin-scale linear optimization model with the ability to evaluate the system’s performance against a reduced inflow scenario in future. Results showed an acceptable match between predicted and observed outflows from the system at selected hydrometric stations. Moreover, an efficient operating policy was determined for Sefidroud dam leading to a minimum water shortage in the reduced inflow scenario.</p> <p class="card-text"><strong>Keywords:</strong> <a
