摘要
变截面吊车梁的疲劳破坏与变截面的支座构造紧密相关。根据变截面吊车梁两种直角突变式支座构造的疲劳性能研究结果,讨论变截面吊车梁直角突变式支座节点的合理构造,并推荐其中一种疲劳性能好、经历过工程实践检验而可广泛推广应用的支座节点构造。
Fatigue failure of variable cross-section crane girders shows a close relationship with the section varying support details. Based on the research results on the fatigue performance of two types of right-angle support details of variable cross-section crane girders, appropriate support details of crane girders are discussed and a support detail with good fatigue performance is proposed, which has been verified by practical engineering and can be widely used.
