Performance Based Seismic Design Theory And Method Of Light&Energy-saving RCS Composite Structure

Light energy-saving RCS composite structure, as a kind of new buildingstructure system, is very potential. Through summing up preliminary studies,the dissertation is devoted to numerical models of nonlinear seismic responseanalysis, elasto-plastic analysis programs and time history analysis methodbased light steel-concrete composite structure. The main researches are asfollows:1、The pseudo static test of high strength concrete columns confined bybutt-welded closed composite stirrups and honecomb steel beam-highstrength concrete columns confined by butt-welded closed composite stirrupsare introduced. The test phenomenon is described and each feature point datais obtained. Using SAP2000software, RCS composite frame is established fortime history analysis and elasto-plastic analysis of structure for whole processis produced for comparing the interlayer displacement angle.2、Pinciple and method of nonlinear time history analysis are expounded.The finite element analysis for a4layer4cross combination scale framestructure and15layer actual frame structure is conducted. According to thetest results, numerical analysis and seismic code, elastic displacement anglelimit and plasticity displacement angle limit between layers are proposed forthe light energy saving RCS composite structure.3、On the basis of experimental study and numerical simulation, combiningwith the current national relevant specification, the light steel-concretecomposite structure seismic design methods are researched. The concept oflight steel-concrete composite structure housing design principle is achieved.The practical formulas for calculating the ultimate bearing capacity ofstructural components and nodes are given.
