梁式桥支座截面横隔梁强度的简易计算方法研究

Study on How to Calculate the Strength of Diaphragm Beam in the Position of Bearing Section in Beam Dridge Easily

横隔梁是桥梁的重要组成部分,使桥梁的纵梁和横梁共同作用、整体受力。但是横隔梁的受力往往比较复杂,通常同时受弯、剪、扭作用,因此给计算带来了一定的难度。另外外荷载(主要指汽车荷载)的作用是如何传递到横隔梁上的也是一个复杂过程,规范等其他论著也很少提及,因此在此提出了一种简单的计算方法。

Diaphragm beam is the important part of a bridge, which makes the vertical beam and cross beam work together. At the same time the force of Diaphragm beam is always complicated, even simultaneously bearing the action of bending, shear, and torsion, that makes the calculation more difficult. In addition it is a complex process how does the action of the dynamic loading passed to diaphragm beam, moreover the codes of bridge are also not mentioned. In the paper a very easier method of calculation is put forward.
