基于不同屋顶方案的轻钢结构抗风性能

为有效增加沿海地区开阔地带厂区轻钢结构的稳定、强度及经济性,针对常用的双坡屋顶及单坡屋顶轻钢结构,运用Midas/Gen、SAP2000与PKPM-STS这3种结构软件中相应模块的有限元分析方法,给出了不同屋顶形式下结构节点及杆件内力、抗风性能等参数分析结果.结果表明:在常用的轻钢结构屋面结构形式中,双坡屋顶抗风性能与单坡屋顶抗风性能在独立分析时前者优于后者;结构整体分析时需要考虑维护系统的参与作用.

Wind resistance of light steel structures based on different roof schemes

In order to effectively increase the stability, strength and economical efficiency of light steel structures in the factories in the open area of coastal areas and aiming at the commonly used double-slope roof and single-slope roof light steel structures, the analysis results of such parameters as structure nodes, rod internal force and wind resistance under different roof forms were given with the finite element analysis method of the corresponding modules in three structural software of Midas/Gen, SAP2000 and PKPM-STS. The results show that among the commonly used light steel structure roof structures, the wind resistance of the double-slope roof is better than that of single-slope roof in the independent analysis, while the participation role of maintenance system should be considered in the overall structure analysis.
