REPORT OF RANDOM TEMPERATURE AND RANDOM CREEP STRESS IN MASS CONCRETE STRUCTURES
-
摘要: 大体积混凝土结构随机温度及随机徐变应力的研究已显得越来越重要.本文从随机环境影响因素、混凝土材料的随机热力学参数、随机绝热温升以及混凝土徐变、老化等多种影响方面对混凝土结构的随机温度以及随机徐变应力目前已有的各种计算方法进行了较为系统地述评,指出了各种方法的适用性以及今后需要解决的问题.Abstract: Research of random temperature and ramdon creep stress in mass concrete structures is becoming more and more important for practical engineering. This paper discusses random environmental factors, random physical parameters, random hydration heat of concrete as well as the properties of concrete aging and creep etc., and reviews systematically various methods for the analysis of random temperature and random creep stress of concrete structures. The suitability of those methods and the key problems needed...
