Lack of authentic methods for design of new structural load resisting systems can always be noticed. Special steel plate shear wall (SPSW) is one of the most operational new lateral load resisting systems, which requires specific design standards. Recently, quite a few instructions have been compiled in the realm of steel plate shear walls. However, there is a clear need for one exhaustive, reliable source to which engineers can refer for simulation, analysis, design, as well as optimum design purposes. Not only does a comprehensive source contain all alternative methods, but it also compares the pros and cons of the methods in an unbiased fashion in order to surpass all designers’ expectations. This thesis is a guideline from which researchers can utilize for study purposes, in that it contains all of the aforementioned qualities of a comprehensive source.
Optimal design of the SPSW system via metaheuristic algorithms is the main objective of this thesis. Structural optimization is one of the most primary function of this algorithms that we want to enhance. Here, improving the performance and efficiency of these metaheuristic algorithms for optimal design of steel plate shear walls by adjusting their parameters and comparing their results has been done.
Present work commences with a literature review of the steel plate shear wall and optimization of this system, and then it discusses various types of simulation modeling of the SPSW and their analysis methods which are recommended in design guides. Furthermore, it deals with design requirements for both low seismic and high seismic loads. In addition, in design section we demonstrate how the main constraints of the steel plate shear wall have been derived. Finally, optimal designs for the low seismic SPSW, high seismic SPSW, and one steel moment frame have been figured.
