摘　　要：详细论述了一复杂体型马铃薯储藏库主刚架的计算、分析与设计过程。该结构主刚架采用冷弯薄壁构件 ,按美国UBC规范进行荷载分析和组合 ;按许用应力法 (ASD)设计冷弯薄壁构件 ;按摩擦型高强螺栓连接设计节点。且考虑了屋面活载不均匀效应、雪压堆积效应和水平地震作用的影响 ,荷载组合复杂。文中设计的冷弯薄壁型钢构件按我国规范GBJ18— 87验算也是满足要求的。This paper detailed the computation, analysis and design of the rigid frame of a potato storage. This storage has a complex shape with two ridges, and the rigid frame is made of coldformed steel structural members. Here, the analysis and combination of loads complied with the requirements of the 1997 edition of Uniform Building Code , the cold form members were designed by the method of Allowable Stress Design , and the bolted joints of rigid frame were designed as frictional connection. The load combination is complex with consideration of the effect of asymmetry distribution of live load, snow accumulation and horizontal seismic load. The cold formed members designed here meet the requirement of our country's code GBJ18—87。
