摘要
文章以某桥主桥2×100m的梁-斜拉组合体系为研究对象,采用ANSYS有限元软件对该桥进行了抗震性能研究,并基于地震时程分析法,评估了该大桥在地震荷载作用下的应力和位移响应情况,找到了该桥的薄弱环节,为该桥的设计提出有益的建议。
With the main bridge 2× 100m beam-stayed combination system of a bridge as the research object,the article used the finite element software ANSYS to conduct the seis- mic performance study of this bridge,and based on the seismic time history analysis meth- od, it assessed the stress and displacement response situation of this bridge under earth- quake load impact, and found the weak links of this bridge, thereby making useful sugges- tions for the design of this bridge.
