| 摘 要： | 以重庆长江大桥复线桥为背景,对原桥主跨跨中的110m钢箱梁重新拟定为组合梁结构形式.运用桥梁专业有限元软件MIDAS CIVIL建立全桥有限元模型,采用反应谱分析方法对新拟定的模型进行抗震计算,得出接头在最不利偶然荷载组合下最大内力值,运用有限元软件ansys建立组合-混凝土结构的接头与钢-混凝土结构的接头.在偶然荷载作用下对两种接头内力进行对比分析.

| Abstract: | According to the Chong Qing Changjiang bridge, replacing the main span of the original bridge steel box girder in 110m with a steel -concrete hybrid bridge structure form, The bridge professional finite element software MIDAS CIVIL to establish the finite element model. Using the response spectrum method for seismic analysis of the proposed new model, By using the software ANSYS to establish the combination of concrete structural joints and steel - concrete structure joints. A comparative analysis oftwo kinds of joint forces in the most unfavorableaccidental loads. |
