摘要
本文将水平荷载所产主的层间剪力在各墙肢间按层间侧移刚度进行分配,每个墙肢按所分配到的作用力分别单独计算。自顶层开始,采取逐层往下递推计算的方法。该方法可用于各层层间刚度相同或不同的联肢剪力墙的计算。
A simplified method for calculating the coupled shear wall structure withuniform or variable story stiffness under the action of horizontal forces hasbeen presented in this paper. The story shear produced by horizontal forces isdistributed between the individual wall legs in accordance with their storyshear stiffness. Each wall leg acted by the distributed forces is analyzedindependently. Beginning from the top story, calculation is conducted downwardstory by story.The pocket computer may be used to calculate the wall leg withsimple programme. Manual computation may be also used to accomplish suchanalysis. The method in the paper is relatively simple and the results are ofsatisfatory accuracy.
