摘　　要：在国内多次发生的雪灾中,发生过多起钢结构房屋倒塌的事故,造成了严重的人员伤亡和经济损失。门式刚架轻型房屋钢结构作为一种对雪荷载敏感的结构形式,其规范也在调整提高对其雪荷载的取值,并给出不同屋面形式下的积雪分布系数。本文以一实际案例,结合多种结构布置形式分别对比不同荷载分布系数下钢架计算结果。In many snowstorms in China,there have been many accidents of steel structure houses collapsing,causing serious casualties and economic losses.As a kind of sensitive structural form to snow load,the specification of the portal rigid frame steel structure is also adjusted to improve the value of snow load and give the snow distribution coefficient under different roof forms.Here I take a practical case,combined with a variety of structural arrangement forms to compare the results of different load distribution coefficients under the steel frame calculations.
