摘　　要：本文研究带刚性连梁的双肢剪力墙及其结构控制性能． 首先， 介绍四种形式刚性连梁的试验研究，即普通钢筋砼刚性连梁、劲性钢筋砼刚性连梁、带摩擦滑动节点的钢筋砼刚性连梁以及带钢支撑摩擦滑动节点的刚性连梁． 由于具有良好的强度、刚度以及强震后易修复的特性， 带钢支撑摩擦滑动节点的刚性连梁最适用于带刚性连梁的双肢剪力墙结构； 其次， 通过理论分析和试验研究证明了： 刚性连梁能有效增加连梁较弱的双肢剪力墙结构刚度，In this paper, the realization methods of coupled shear walls with a stiffening beam(CSWSB) and its passive control behavior are investigated. Four types of stiffening beams, namely, RC stiffening beam, RC stiffening beam with friction_damped surfaces, SRC stiffening beam and stiffening beam with steel bracing and friction_damped joint, are examined. As the strength, stiffness and the deformation ability can conveniently be controlled and the repairs of structure can easily be carried out after strong earthquake, the stiffening beam with steel bracing and friction_damped joint is the most suitable one for CSWSB. The results of experimental and theoretical research of CSWSB show that the presence of a stiffening beam can considerably increase the stiffness of coupled shear walls with weaker lintel beams and CSWSB has favourable aseismic behavior.
