双向限制弹性地基板块随机温度应力分析

Analysis of Random Thermal Stresses of Concrete Slabs Restricted on Elastic Bases

本文将随机过程的数学理论引入结构温度场和温度应力的分析中,对于受双向限制弹性地基土的混凝土板块,具体分析随机环境温度变化对其温度、应力和随机数值特征的影响,并通过算例分析年、日变化气温及有关参数的影响规律。

In this paper, an approximate analytical method a based on the theory of stochastic process is developed to analyze the random temperature and thermal stresses in concrete structures, which are caused by random variation of the environment temperature. To the concrete slab restricted in horizontal and perpendicular directions on the elastic base, numerical examples are given to show the effect of some relevent factors on the thermal stresses and the standard deviations of stresses.
