室内滑雪馆超长混凝土结构温度应力分析与设计

Temperature Stress Analysis and Design on Over-long Concrete Structure of Indoor Ski Resort

结合某室内滑雪馆,考虑温度变化效应和混凝土的收缩徐变效应,对超长混凝土结构的楼板应力采用有限元软件进行分析。根据计算分析的温度趋势结果,对应力较大的区域配置温度筋,并通过控制后浇带封闭时间及温度及其他施工、设计措施来解决超长混凝土结构温度应力的问题。

According to the project of Indoor Ski Resort,considering the effect of temperature change,shrinkage and creep of concrete,the floor stress of over-long concrete structure is analyzed by finite element analysis method.According to the calculation and analysis of temperature trend,the temperature reinforcement should be configured in the area with large stress,the problem of temperature stress of over-long concrete structure is solved by controlling the sealing time and temperature of post cast strip and other construction and design measures.
