Optimization method of shear wall structural design based on genetic algorithm
High-rise structures of shear wall structural system are prone to the problem of eccentric layout of shear walls,which also causes the problem of their insufficient torsional resistance under horizontal action.By analyzing the advantages and applicability of genetic algorithm,the genetic algorithm was determined to be used to achieve the problem of optimizing the torsional performance of shear walls.The setting of the conditions of the optimization method based on genetic algorithm was discussed specifically,and the specific steps of the optimization of shear walls based on genetic algorithm were described.Taking an engineering building structure model as an example,the simplified model was optimized based on genetic algorithm for 400 iterations,and the original model of the optimized building was verified.The results show that the optimization of shear wall structure based on genetic algorithm is effective,and the optimized shear wall structure can effectively reduce the floor displacement ratio under horizontal and torsional action,which proves the feasibility of optimization of high-rise shear wall structure based on genetic algorithm.
