摘要:
以黄桷湾特大桥为工程背景，选取轴压比、梁墩刚度比、系梁布置形式及柱肢混凝土强度等级为设计参数，应用Midas Civil有限元软件构造了20座三跨对称桥梁计算模型。研究E1地震作用下钢管混凝土双肢格构墩连续梁桥主要控制截面参数地震响应，探讨各设计参数对钢管混凝土双肢格构墩连续梁桥抗震性能的影响规律，并对全桥进行优化验证。研究结果表明:轴压比对地震作用下结构内力和位移有一定影响，建议控制在0.15~0.25；梁墩刚度比对结构的抗震性能影响较大，控制在4.08~10.90时结构的内力分布更加合理；核心混凝土的强度在C40~C50时取值较为合理。
Abstract:
With the Huangjuewan grand bridge as engineering background, taking axial compression ratio, stiffness ratio of beam and pier, layouts of lacing tubes and strength grade of column concrete as design parameters, 20 finite element models of three-span symmetric bridges were built by using Midas Civil engineering software. The seismic response of the major control section parameters of continuous beam bridges with concrete-filled steel tube two-element laced pier under the action of E1 earthquake was studied. Effects of the design parameters on the seismic performance were discussed, and the whole bridge was optimized and validated. Research results show that the axial pressure ratio has certain effects on the internal force and displacement of the structure under the action of earthquake and is suggested to be controlled during 0.15 and 0.25; the beam-pier stiffness ratio has a great effect on the seismic performance of the structure, and the internal force distribution of the structure is more reasonable when it is controlled within the range of 4.08~10.90; the strength of core concrete is reasonable with its value being among C40 to C50.
