摘要
通过分析自然界温度变化的一般规律,分析引起结构温度作用的主要气象因素,描述了日照辐射、气温、风速的基本变化规律,对日照温差、骤然降温等温度变化对桥梁结构、建筑结构、大体积混凝土结构、特种结构等混凝土结构的影响进行了研究和总结。针对现行混凝土结构设计规范中对温度作用只是采取构造措施的现状,提出了在混凝土结构设计中考虑温度作用组合的建议。
After analyzing the general regnlation of temperature changes in nature, some climate factors that influence temperature effect to structure are analyzed. The climate factors are mainly sunshine radiation, the temperature, the wind speed. The research aimed at the reaction of different concrete structures, such as bridge structure, building structure, the mass concrete structure and special structure, to temperature changes caused by the sunshine temperature difference and by sudden decrease of temperature. Considering the situation that temperature effect is only considered by construction according to the present design code of concrete structure, it is proposed to consider temperature effect combination in the design of concrete structure.
