摘　　要：从某体育馆转换桁架提取一部分,分别分析其次应力分布大小及规律,初步探讨次应力产生的原因以及杆件类型与次正应力比的关系,为以后施工、设计提供参考。Taking one part of conversion truss in one stadium as example the value and regularities of the distribution of secondary stress are respectively analyzed. Reasons caused the secondary stress are discussed as well as the relationship between type of member bar and stress ratio in order to provide references for construction and design in the future.
