The values of the lateral and vertical vibration acceleration of PCT beam are all under the safety limits regulated by Code for Rating Railway Bridges.
PCT梁的横、竖向振动加速度值都不大，均在《铁路桥梁检定规范》规定的限值以内；
2
The effect of different mathematical models on lateralvibration analysis of multi-span simple beam bridge is discussed in this paper.
讨论了铁路多跨简支梁桥不同计算图式对横向振动分析结果的影响。
