Calculation of Longitudinal Connected Slab Reinforcement Considering Expansion and Contraction of Bridge
为优化桥上CRTSⅡ型板式无砟轨道纵连底座板配筋设计,推导了纵连底座板刚度折减计算方法.分析了纵连底座板上的纵向力,提出其配筋设计应考虑伸缩力,并确定了伸缩力的组合系数.基于极限状态法,建立了考虑伸缩力的纵连底座板配筋计算方法,并给出了大跨度连续梁桥纵连底座板配筋的算例.研究结果表明:考虑伸缩力的纵连底座板配筋计算方法对提高其耐久性更有利,特别是对大跨度连续梁桥.
To optimize the reinforcement design of longitudinal connected slab for CRTS II -type slab ballastless track on bridge, a computational method of stiffness reduction on the longitudinal connected slab was derived. Longitudinal forces acting on the longitudinal connected slab were analyzed. It was proposed that the reinforcement design of longitudinal connected slab should take the longitudinal force resulted from bridge expansion or contraction into account,…查看全部>>
