摘　　要：在对1 000 kV变电架构进行风荷载受力分析时,以单跨架构为例计算风振系数zβ并判断其合理性.按联合架构,计算不同风向时架构的受力情况及风荷载产生的内力占总内力的情况,从而为1 000 kV变电架构及类似结构的风荷载计算提供参考.When analyzing 1 000 kV substation truss structure at wind load,using single-oulet portal frame as an example,we calculate dynamic effect factor of wind at a height of βZ and demonstrate if it is right.Taking a combined truss structure for example,its internal forces under wind load in different directions are analyzed;and the proportions of internal forces under wind load to ones under overall load are analyzed too.From above analysis,the results can be provided references for 1 000 kV substation truss str...
