针对混合结构房屋顶板与顶层墙体间的温差及弹性模量不同所产生的温度应力 ,介绍了 3种适用于不同情况下的温度应力分析方法 ,这些方法可用于顶层墙体温度应力的理论分析、工程设计及工程加固前鉴定过程中的温度应力验算 .按弹性理论 ,应力函数法属于较精确的温度应力分析方法 ;在实际结构计算中 ,由于用较精确分析方法计算复杂 ,可采用简化后的近似温度应力分析方法 ;当墙体开洞较多时 ,用弹性力学方法求解很复杂 ,实际设计中可采用结构力学方法分析温度应力 .
According to the temperature stress caused by the difference of temperature and elastic modulus between roof and top wall of hybrid structure, three kinds of temperature stress analysis methods suitable for different situations are introduced, which can be used in theoretical analysis of thermal stress of roof wall , The engineering design and verification of the temperature stress in the process of pre-reinforcement engineering.According to the elastic theory, the stress function method belongs to the more accurate method of temperature stress analysis.In the actual structure calculation, due to the complication of calculation by more accurate analysis method, Of the approximate method of temperature stress analysis; when the wall hole more, the use of elastic mechanics method is very complicated, the actual design of structural mechanics can be used to analyze the thermal stress.
