水平地震作用下框支剪力墙结构的变形研究

对工程结构中常用的底部为多层大空间的框支剪力墙结构采用分区混合法，进行水平地震作用下结构的变形研究。将框支剪力墙结构分成转换层上部剪力墙结构和转换层下部框架剪力墙结构两部分，采用子结构法进行分析。在水平地震作用下，转换层上、下部先分别按剪力墙结构和框架一剪力墙结构的变形曲线公式计算其变形，再充分考虑上下两种不同结构的变形协调性，推导了框支剪力墙结构在水平地震作用下的侧移曲线公式，并给出了方便结构侧移曲线计算的图表。方法简单实用，可用于地震区高层建筑结构的初步设计。

Distortion research of shear wall structure supported on frame under earthquake actions

Shear wall structure supported on frame-shear wall structure is used frequently in civil engineering.Based on the zonal mixed method,the distortion of shear wall structure supported on frame under earthquake actions is researched in this paper.The whole structure can be divided into two parts which are shear wall structure above transfer story and frame-shear wall structure under transfer story,and can be analyzed in substructure method.Under earthquake actions,the distortions of shear wall structure above transfer story and frame-shear wall structure under transfer story can be calculated by their intrinsic horizontal displacement formulas respectively.Considering the harmony of distortions of the two divided structures,the horizontal displacement formulas of whole structure is deduced strictly,and some figures of the horizontal displacement are given.This method is proved that it is accurate and convenient enough for use when tall buildings are designed in earthquake zone during the preliminary design.
