摘要
本文的主要研究内容有:介绍二种最基本的应力-温度途径下混凝土变形性能试验,分析了不同应力-温度途径下混凝土变形的巨大差别,提出了高温时应力变形和应力下温度变形等概念,建立了任意应力-温度途径下混凝土本构关系的计算公式和方法,并用算例予以说明。
The main contents presented in this paper are. introducing the tests for measuring the strain of concrete under two basic stress-temperature paths; comparing and discussing the considerable difference of the total strain of concrete obtained from these two paths; suggesting the concepts of the stress-deformation under high temperature and the thermal-deformation under stress; establishing the formulas and method for calculating the constitutive relation-ship of concrete under any stress-temperature path and demonstrating them by a numerical example.
