摘要
以连续梁桥为背景,采用MIDAS Civil有限元软件对不同墩高及直径分别建立有限元计算模型,对其自振特性及延性影响进行分析,着重分析不同直径及墩高桥墩内力及变形等地震反应变化规律,并对E2地震下变形能力进行验算。
Taking a continuous girder bridge as the background, the finite element software MIDAS Civil is used to separately establish the finite element calculation models for the different pier heights and diameters.Its self-vibration characteristics and ductility effect are analyzed. The change rules of seismic response of pier inner force and deformation of the different diameters and pier heights are analyzed in detail. And the deformation ability under E2 earthquake is checked and calculated.
