变刚度、变层高的框-剪结构计算

Calculation of Frame-Shear Wall Structures with Different Stiffness and Different Floor Height

本文不采用连续化假定,由框架抗侧刚度和连系梁转角刚度的定义,直接给出总剪力墙的计算简图.以顶部节点转角为初参数,用结构力学方法建立节点相对水平位移与转角之间及相邻节点转角之间的关系,自上而下递推至墙底,由墙底转角为零的变形条件求出顶部节点转角,使问题得到解决.

The paper is not referred to as the. 'continuum approach'. The simplified calculation model of frame-shear wall structure is directly given by the definition of frame stiffness in resisting horizontal displacement and the definition of rotation stiffness for the coupling beam. The top joint rotation is adopted to be elementary parameter. The relationships between joint rotation and its relative horizontal displacement or its adjacement joint rotation are set up by means of the general principle of Structural Mechanics. The calculation order is from the top to the bottom of the wall. At last, the top joint rotation can be obtained, and then, the solution to the problem can be found perfectly.
