混凝土结构温度内力数值分析

Numerical analysis on internal force of reinforced concrete structure caused by temperature

为研究混凝土结构的温度效应,利用ANSYS对混凝土框架、框架—剪力墙和剪力墙等结构在温度变化作用下的变形特点和内力分布规律进行系统分析.对具有不同纵向长度、楼层数和建筑体形特征的结构分别建立计算模型,在假设建筑物内外无温差和有温差两种温变条件下进行计算分析,从中得到各种结构温度变形和内力分布的基本规律,其主要结论对结构工程师具有实用价值.

To study temperature effect of concrete structures, the numerical analysis on temperature deformation and internal force caused by temperature distribution of reinforced concrete frame structures, frame-shearwall structures and shearwall structures are done using ANSYS. Typical computational models are established respectively for the structures with different longitudinal lengths, storeys and forming characteristics, which are analyzed under the assumption with or without temperature difference between inside and outside the structures. The temperature deformation and internal force distribution are obtained. The main conclusions are valuable to structure engineers.
