Abstract: Sharewalls with steel support plate enclosed are excellent new anti-lateral force members.  This paper is based on the analysis of the buckling behavior, stiffness and stability under working conditions etc. of this member through finite element analysis software SAP2000, which considers multiple constrains including the effect of the concrete, the width-to-tluckness ratio of the steel plate, and constrains of joints etc. It provides many guides for design in the future.
Keywords: shearwalls with steel support plate enclosed; finite element; buckling analysis
