摘要
砌体结构的墙体裂缝危害结构安全及房屋使用功能。简单介绍了热应力有限元方法。并以此为基础,计算了砌体结构顶层墙体及屋面板在温度荷载作用下的整体应力分布及结构形变,分析了砌体结构在温度应力作用下裂缝形成原因。通过分析可为砌体结构温度裂缝防治提供依据。
The temperature crack of masonary structure endangers security and application functions of buildings.This paper introduces finite element method of temperature stress and calculates the stress distribution and deformation of masonary of top floor and roof concrete plane at temperature load based on this method,analyses the reason of crack caused by temperature stress.Whick can offer a basis for the prevention of temperature crack of masonary structure through the analysis.
