Frame-shear structure wall layout optimization method based on improved particle swarm algorithm

The invention provides a frame-shear structure wall layout optimization method based on an improved particle swarm algorithm, provides an adaptive mutation strategy based on population diversity and awhole-process dynamic adjustment factor, and improves a standard particle swarm algorithm. According to the technical scheme, hierarchical coding is conducted on the position and the size of the shear wall in the structure, various performance index limiting values in the specification serve as constraint conditions, the concrete dosage obtained after shear wall bottom tensile stress weighting isconsidered as a target function, and the shear wall layout is optimized through an improved particle swarm algorithm. The invention has the beneficial effects that after the improved particle swarm optimization algorithm is adopted, efficient heuristic search can be carried out on a large number of individuals, the analysis efficiency of the shear wall layout problem is greatly improved, the useamount of wall materials is
