高层框-剪结构中框架地震内力的确定

Determination of Seismic Forces Acting onFrame in High-rise Frame-Shear Wall Structures

通过模型试验及分析找出框架最不利地震内力状态，给出各种情况下框架楼层地震剪力修正系数，由此提出一种考虑剪力田刚度退化框．剪结构框架地震层剪力的实用计算方法。

Based on the experimental data and analysis, the seismic internal forces of the frame under themost unfavourable condition in high-rise frame-shear wall structure have been obtained. Coefficientsof correction for the seismic force acting on the frame of such high-rise structure are presented, anda practical method for calculating the seismic forces acting on these frames in consideration of thedeterioration of the stiffnesses of shear walls has been put forward.
