剪力墙结构的静动力分析

Analysis and Dynamic Analysis of Shear Wall Structure

以西北工业大学南村4#、5#小高层住宅为例,进行了剪力墙结构的壳元模型在不同受力状态的静力分析、模态分析、动力分析.分析剪力墙结构的基本振型、结构的侧移和层间侧移、结构的等效应力等,结果表明:该结构的最大层间侧移为二层、最大应力值在二层底部、底部的一到五层应力相对较大,一般在工程中需要加强.

Taking the shear wall structure （4# and 5# building of the south residential area of the Northwestern Poly -Technical University） for example, analyzes and designs shell model of the shear wall structure. According to different combine-loads of the structure suffered, static analysis, mode analysis, transient dynamic analysis are studied, including structure＇ s natural period value, structure displacements, story drifts and equivalent stress of structure. The conclusions are gained as follows： first, the maximum value of story drifts is in the second story; secondly the maximum stress is at the bottom of the second story; the stress is relatively greater in the bottom part or the first to fifth stories, whose parts should be generally enhanced in actual engineering.
