摘要
对多跨门式刚架的风荷载与地震作用进行了探讨,分析比较了"规范"(GB 50009-2001)与"规程"(CECS 102∶2002)中风荷载计算的不同,并对7度地震区地震作用效应组合和其他荷载效应组合进行比较,提出了不同情况下风荷载计算问题与7度区是否需要抗震验算问题的解决方法。
The mechanical behaviors of multi-span steel portal frame under wind load and the seismic action are discussed, The differences of wind load calculation in code （GB 50009-2001） and specification （CECS 102：2002） are comparatively analyzed, Further comparison is also made on combination of seismic effects and combination of load effects in seven degree earthquake zone, Practical measures are proposed to resolve the wind load calculation problem under different situations and question that whether require seismic checking calculation in seven degree earthquake zone,
