水平荷载作用下框架-自复位墙结构受力分析
Mechanical Analysis of the Framed Self-centering Wall Structure under Lateral Loading
摘要
Abstract
Adopting the "rigid body-MDOF" model,the basic equations of the pin-joined and rigid-joined system of the framed self-centering wall structure under lateral loading were established respectively with the cooperative work between the frame and self-centering wall taken into account.The analytical solutions of internal force and displacement responses were given and the mechanical behavior of the framed self-centering wall structure was investigated preliminarily.It is shown that the lateral displacement curve of the framed selfcentering wall structure is linear along the height,which indicates that the story drift ratio remains constant along the height.After equipped with prestressed tendons and dampers,the overall stiffness of the framed selfcentering wall structure are enhanced obviously and the shear force demand of the frame is lowered.The restraint provided by the coupling beams can also effectively reduce the responses of the framed self-centering wall structure under lateral loading.The overall performance of the framed self-centering wall structure under lateral loading ranges between that of the frame wall structure and the frame structure.关键词
