摘要
以 3种不同跨度的铁路标准预应力混凝土T梁和双柱式轻型墩为研究对象 ,分别建立 4种不同的计算模型 ,较为系统地分析墩梁频率比对桥跨结构动力性能的影响规律 ,得出计算公式 ,对桥梁状态评估和故障诊断都具有非常重要的参考价值。
Four different kinds of computation models were established for three different spans of railway standard PC T beam and double cylindrical light pier. A systematic analysis was made of the law of the impact of pier-beam frequency ratio on the dynamic performance of bridge span structure,and a computation formula was determined,which is of significant value for assessment of bridge status and diagnosis of failures.
