摘　　要：本文以四川省游泳馆为例，在对３９ｍ屋架钢结构进行多种科目检测并取得较完整数据的基础上，按现行有关规范对钢管结构按空间桁架进行了全面的计算分析，同时用Ｋ因子判据法进行了应力腐蚀形成后结构的抗断裂安全度推断，提供了腐蚀气氛下管型钢屋架结构承载力可靠性评定的较全面的鉴定资料。Based on the multi-subject detections and comprehensive datum,the 39m steel roof struss,sichuan provincial Natatorium which as a space frame is calculated and analyzed thoroughly according to currrent codes for tubular structures.Meanuhile,the predictions for fracture-resisting safety after forming the stress corrosion are conducted using K-factor criterion.A comprehensive appraisal information on reliability evaluation is provided for tubular steel roof truss under corrosive atmosphere condition.
