Optimization Design of Reduced Beam Section Using Genetic Algorithm

Engineering designs that ensure the safety of residents while ensuring economic issues is the same as modern seismic design with the advantage of ductility, the structure is designed so that its final elastic force is proportional to creating a crack in the structure. In steel flexural frames, joints with the reduced cross-sectional area have been extensively tested and have acceptable performance under different cycle loads. One of the weaknesses of the last research was the lack of attention to reducing costs. Also, we can conclude that most of the research has been done on a specific type or most of them have been trial and error, they have only evaluated the results and have not tried to achieve the best and most optimal dimensions of these connections. In this study, the analysis of several connections in different types has been done and the analyzes have been optimized. Also, it has been tried to model Reduced Beam Section (RBS) connections using ABAQUS software by dynamic analysis and numerical methods, finally, after analyzing the desired connections, the output of the performed analyzes is transferred to MATLAB using a genetic algorithm. Finally, the optimized models are first reviewed in terms of maintaining stability and then compared with other RBS models that are not optimized. After that comparisons have been done with other optimized algorithms, and the results obtained from modelling and analysis are presented. The energy entering the structures has always been considered by the building engineering community due to lateral forces such as earthquakes.
