| 摘 要： | 地震输入问题一直是工程结构抗震研究所关注的焦点.大跨度桥梁结构各地面支承距离较大、延伸较长,进行进震反应分析时应考虑各支承处地震波的不同(多点激励)以及地震波有限波速传播所引起的行波效应.文章以洛河特大桥为例,进行了基于多点激励与行波效应下的动态时程地震反应分析,并比较了考虑多点激励与行波效应对该桥各项地震响应的不同影响.

| Abstract: | Earthquake input pattern has become a privcipal focus in te research on earthquadke-resistance of engineering structures.For long-span bridges,the more rational method for seismic response analysis should be performed considering the multiple support excitation and traveling wave effect.In this paper,the methods of seismic response analysis for Luohe bridges considering traveling wave effect and the seismic responses are established.This paper also compares the different effects between multipl support excitation and traveling waves to the bridges. |
