摘要
本文就建筑结构在温度作用下热传导过程中环境温度取值、多层材料中界面温度的确定、杆件截面内的温度分布以及杆件温度变形受约束时杆端的约束内力、结构温度内力计算、杆件截面设计等一系列问题提出了计算方法和设计建议。
In this paper, the calculation method of internal forces in building structures under temperature action is presented with suggestions in design set forward as well. The method concerns the following problems: the adoption of the values of environment temperature in the course of heat conduction in building structure, the determination of the boundary layer temperature in multilayer materials, the distribution of temperature within member sections, the restrained forces in the ends of member where the deformation are restrained, the calculation of the internal forces induced by temperature in structures and the design of member sections.
