从桥梁翼缘板的横向防撞强度验算谈边梁的横向配筋

On Transverse Reinforcement based on Computation Checking of Transverse Crash Strength of Bridge Flange Slab

针对设计人员在桥梁上部结构设计中,往往忽视横向碰撞力作用下边梁或边板悬臂等薄弱环节的验算问题,对一座特大桥的钢筋混凝土墙式护栏的翼缘板进行横向防撞强度验算,提出了桥梁边梁配筋设计时应注意横向配筋严重不足的问题。

To counter the tendency that in the design of bridge superstructure, computation checking for weak points such as the side beams or side plate suspension under transverse crash force has often been neglected by the designers, computation checking of transverse crash strength is made on flange plate of a box-girder bridge, it's suggested that more attention should be paid on the serious insufficient of transverse reinforcement in the design of side beam reinforcement.
