Performance-based seismic design and evaluation of steel column-steel plate shear wall coupled system
The steel column-steel plate shear wall coupled structure(SC-SPSW)uses steel coupling beams to connect the steel plate shear wall and the steel columns on both sides.The system can make full use of the coupling effect between steel plate shear wall,coupling beams and steel columns to improve the shortcomings of traditional steel plate shear walls and have favourable seismic performance.This paper adopts plastic design based on energy concept,and derives the design method of SC-SPSW system by combining with relevant codes.Using SAP2000 software,twelve SC-SPSW system cases with different heights and coupling ratios(CR)were designed and carried out by static analysis and dynamic time history analysis to investigate the yielding mechanism and the influence of the coupling ratio on the seismic performance.It is shown that all SC-SPSW systems applying this design method can achieve the ideal yielding mechanism with excellent seismic performance.Suggestions are also made in terms of the appropriate selection of CR for different structural heights.
