Abstract
To address the limitations of Particle Swarm Optimization(PSO)in the design of high-rise buildings,this study proposes a modified PSO algorithm to enhance structural wind resistance.By optimizing the initial position settings and position variable update mechanisms of the algorithm,and incorporating the modal shape interference method,refined control of wind-resistant design for high-rise buildings is achieved.A 600-meter super-tall building was selected as the case study,with wind tunnel testing and dynamic wind load analysis conducted.The results demonstrate significant reductions in equivalent static wind loads(ESWLs)at the building base:Horizontal shear force,vertical shear force,and spatial shear force decreased by 2.32%,2.40%,and 3.01%,respectively,while horizontal bending moment,vertical bending moment,and spatial bending moment were reduced by 1.09%,2.26%,and 2.23%,respectively.The application of the improved PSO algorithm combined with the modal mode interference method in the wind resistance design of high-rise buildings can effectively improve the structural safety.关键词
