超长结构设计的温度效应分析

Temperature Effect Analysis of Super-long Structure Design

文中以安徽亳州市谯城区某商业综合体为例,通过实际工程案例,对温度效应下的超长结构进行分析。结果表明,首层及屋面楼层温度效应影响最大,降温下楼层主要产生的拉应力,在同高度楼层中央拉应力最大,向两端则逐渐减小。

Taking a commercial complex in Qiaocheng District,Bozhou City,Anhui Province as an example,this paper analyzes the temperature effect of the ultra-long structure through the actual project.The calculation results show that the temperature effect of the first floor and the roof floor is the biggest.The main tensile stress of the floor under cooling is the largest in the center of the floor of the same height,and it gradually decreases to both ends.
