摘要
以某立交的平曲线半径60 m的一联钢混凝土组合梁为例,详细介绍了小半径曲线钢混凝土组合梁的设计及计算分析,指出对该类桥型的设计计算应从构造、计算方面充分考虑弯桥效应,并建议采用空间建模分析其受力情况,以便及时采取措施,将扭转带来的不利影响控制在规范允许的安全范围。
Taking a steel concrete composite beam of a plane curve radius of 60 m as an example,and this paper detailed analyzed the design and calculation analysis of small radius curve steel concrete composite beam,pointed out should be fully considered curved bridge effect from construction and calculation aspects to the design calculation of this bridge structure,and recommended using space modeling to analysis the force situation,in order to take timely measures,made the adverse effects caused by reverse in a safe allowed range.
