上、下行钢板梁桥加固后横向位移计算

The Calculation of Transverse Displacement of Reinforced Parallel Steel Plate Beam

以结构力学为基础,利用加固前对钢板梁桥测得的横向位移,提出了一种通过反算出列车等效横向摇摆力来计算加固后钢板梁桥的横向位移的方法.结果表明此种方法简便有效,可以作为一种对上、下行钢板梁桥两桥连接加固后的位移计算的一种方法.

This paper presents a method to calculate the train equivalent transverse swayforce with the help of the measured transverse displacement before reinforcing the bridge.With the calculated result,the transverse displacement of the reinforced steel plate beam by applying the knowledge of construction mechanics and flexibility mechanics.
