摘　　要：通常在以往的钢构件吊装时吊点高度的选择根据经验来判断,而对于超大跨度的钢构件吊装则需要更多的理论为基础,确定出合理的吊点高度,给出构件在吊装过程中的性能变化,确保施工安全性和经济性。以在建的杭州国际博览中心项目为载体,给出了72m大跨度钢管桁架合理的吊装方法,分析了吊点高度对钢管桁架受力性能的影响。In the past, the lifting height of the steel components often depend on experience, however, study on lifting method of super large-span steel components is based on theory. In order to ensure the construction safety and economy, reasonable lifting height and performance changes of components in the lifting process need to be determined. In this paper, taking the Hangzhou International Expo Center project for example, the lifting method of 72m span steel tube truss and influence of lifting height on the performance of steel tube truss were put forward.
