当前兴建高层建筑日趋增多,随着高度的增加,风力的影响变为十分重要,通常沿结构全高利用抗弯框架和剪力墙共同来承担侧力是有利的。由于这个原因,剪力墙与抗弯框架之间的相互作用是一个重要的结构课题。并联剪力墙(图1)的精确分析是比较麻烦的,一般利用不同的办法以避免所需的大量的计算工作量。本文提供了一种实用的近似法,它是基于Pippard教授所建议的连续介质理论的假设。剪力墙的转角可用一二阶微分方程来表示。微分方程的解给出了:
The number of high-rise buildings currently under construction is increasing day by day. As the altitude increases, the influence of wind power becomes very important. It is generally advantageous to use the flexural frames and shear walls together to take side forces along the full height of the structure. For this reason, the interaction between shear walls and flexural frames is an important structural issue. The accurate analysis of the parallel shear wall (Figure 1) is cumbersome and generally uses different methods to avoid the large amount of computational effort required. This article provides a practical approximation that is based on the hypothesis of the continuum theory proposed by Professor Pippard. The corner of the shear wall can be represented by a second-order differential equation. The solution of the differential equation gives:
