武汉体育中心体育馆主体结构为复杂超长结构,其温差效应不容忽视。采用ANSYS有限元软件进行计算分析,得到了该结构由于温差产生的变形和内力的分布规律,并通过采用侧向约束刚度较小的框架结构、控制主体结构闭合时的环境温度等设计措施减小温度应力的影响。结构现已投入使用5年多,经历了多个温差周期,没有出现明显的温度裂缝,说明达到了设计要求。
The main structure of Wuhan Sports Center Gymnasium is complex and super-long structure, its temperature difference effect can not be ignored. Using ANSYS finite element software to calculate and analyze, the deformation and internal force distribution of the structure due to temperature difference are obtained. By adopting the frame structure with less lateral restraint rigidity, the design measures such as controlling the ambient temperature when the main structure is closed are reduced Effect of temperature stress. The structure has been put into use for more than 5 years, experienced a number of temperature difference cycles, there is no obvious temperature cracks, indicating that the design requirements have been met.
