框──剪体系截肢的性能分析

Optimum Level of Curtailment

本文采用连续介质模型，对框架—截肢剪力墙结构体系的性能作了一个分析，为墙肢削减提出理论依据，并为找到削减的最佳高度范围提供一种方法。由此看出：在某一高度范围内将剪力墙截断，可以使其对结构顶部侧移的影响忽略不计，同时还可减少截断部位以上的框架受力，从而有助于降低成本和空间平面布置。

This article deals with some behaviors of curtailed wall-frame structures, which are on the basis of continuum model. According to the results, we can obtain guidence for the optimum level of wall curtailment to cause a minium increase in the top deflection. Above all, it is beneficial to reduce the forces in the upper part of the frame and more economical
