摘要
计算分析了高速铁路常用跨度 ( 4 0 + 5 0 + 4 0 )m三跨连续结合梁的弹性和塑性极限承载力 ,并对其不同意义下的安全性作了评价 。
The three-span(40+50+40)m continuous steel-concrete composite girder is commonly used in some bridges of the high-speed railway.In this paper,the elastic ultimate state and plastic ultimate state of the continuous steel-concrete composite girder are studied and its security at different states is also evaluated,which may be a reference for design.
