Research on Performance-Based Seismic Design Method of Steel Grid Walls
摘要
Abstract
The existing specifications are more perfect for the design method of steel plate shear wall,but there is a lack of research on the design method of steel grid wall,which has enough stiffness,ductility and lateral bearing capacity.In order to improve the seismic design of steel grid wall system,this paper proposes a performance-based seismic design(PBSD)method of steel grid wall.Based on the performance characteristics of steel grid wall structure,the seismic performance target,failure mode and yield displacement of steel grid wall structure are determined.Based on the principle of energy conservation,the design base shear force of the structure under a given seismic level is calculated.The distribution of seismic horizontal force is obtained based on the lateral force distribution mode of the structure under earthquake.The plastic design formulas of steel grid members and the elastic design formulas of edge beams and columns are derived.In order to verify the feasibility of the proposed method,the method is used to redesign the actual steel frame-steel plate shear wall structure into steel frame-grid wall structure,and the elastic analysis and dynamic elastic-plastic analysis of the redesigned structure are carried out to provide reference for the seismic design of steel grid wall structure.关键词
