某商业大跨楼盖的舒适度计算分析

CALCULATION AND ANALYSIS OF COMFORT OF LARGE-SPAN FLOOR OF A COMMERCIAL BUILDING

因某钢结构商业及商业街项目,平面较为复杂,钢梁跨度较大,容易出现舒适度问题。文中通过简化计算方法和有限元分析方法,对该项目大跨楼盖的舒适度进行了计算分析。结果表明该商业的大跨楼盖部分的舒适度满足现行规范的要求。两种分析方法的结果较为接近,适用于指导规则的楼盖布置,对于复杂楼盖,需采用有限元分析进一步复核。

For a steel structure commercial street project,the structure is complicated with large span steel beam and subjected to comfort problems.In this paper,the comfort of the large-span floor of the project was calculated and analyzed by simplified calculation method and finite element analysis method.The results show that the comfort level of the commercial large-span floor meets the requirements of the current codes.In addition,the results of the two analysis methods are relatively close,and the simplified calculation method is suitable for the floor layout of the guiding rules.As for complex floors,finite element analysis needs to be used for further review.
