Analysis of seismic performance of prefabricated seismic building wall based on ANSYS
基于ANSYS的装配式抗震建筑墙体抗震性能分析

摘要

装配式建筑是我国一种新型的建筑形式，其建造速度快、生产成本低。为了研究装配式结构墙体的抗震性能，在分析现有抗震墙体结构组成的基础上，结合实际工程——万科都会锦悦苑6号楼，利用ANSYS有限元软件建立了装配式墙体建筑的有限元模型。墙体单元由墙板及下部固定组件组成，两块墙板之间设有连接组件，两块墙板之间的连接限位采用连接板实现。分析新型抗震墙体的振型、应力、应变等抗震性能是否符合相关规范的要求，并进行进一步的调整。利用有限元分析软件建立了6个不同振型的有限元模型并进行计算，模型的破坏模式和抗震性能与预期试验结果基本一致，验证了有限元模型的有效抗震性能。

Abstract

Assembly type buildings is a new form of buildings in our country. It can build quickly and lower cost of production. In order to study the seismic performance of prefabricated structural wall, based on the analysis of the structure composition of the existing seismic wall, through the practical project, Vanke Metropolitan Jinyue Yuan No.6 building, the finite element model of prefabricated wall building was established by ANSYS. The wall unit comprises a wall panel and a lower fixed assembly, a connecting assembly between two wall panels, and a connection limit for two wall panels is implemented by providing a connecting plate. It is analyzed whether the seismic performance of the vibration mode, stress and strain of the new aseismic wall conforms to the requirements of the relevant codes, and further adjustment is made. Using the finite element analysis software, six finite element models with different vibration modes are established and calculated. The failure modes and seismic performance of the models are basically the same as the expected experimental results, which verify the effective seismic performance of the finite element model.
