基于ANSYS的框架砌体填充墙温度应力分析

Analysis of Temperature Stress of Filled Walls in Framed Structures Based on ANSYS

摘要: 填充墙对框架结构的承载力、刚度及其变形性能都有着很大的影响。在工程实践中，框架结构砌体填充墙开裂问题相当严重，其中温度应力是主要原因之一。本文对简单框架填充墙进行ANSYS有限元分析，改变填充墙的跨度、开窗面积以及设置构造措施(构造柱或窗台梁)，观察最大位移、最大第一主应力、墙体平均应力的变化规律，从而寻找出减小温度应力的措施，为工程提供实用的技术支持。

Abstract: The filled wall has great influence on the bearing capacity, rigidity and deformation properties of framed structures. In the application, the cracking problem of masonry filled walls in framed structures is quite serious, and one of the main reasons is the temperature stress. This paper conducted the simulation analysis of a simple framed structure with filled walls through ANSYS software, then observed the change rule of the maximum displacement, the maximum first prin-cipal stress and the average wall stress by changing the span, window area of the filled wall and setting up structural measures (structural column or ledge beam), in order to search for measures of reducing temperature stress and supply the technical support for engineering.
