摘要
以连续梁桥为例,采用非线性有限元方法,基于梁理论的纤维单元模型,计算在地震激励下钢筋混凝土桥墩的响应,结果表明:大震激励下,桥墩产生了塑性变形。
A continuous girder bridge was taken as an example for simulation, according to the principle of the non-linear finite element method, based on the fiber unit model of beam structure, an approach is presented for the ultimate load capacity analysis with dumbbell sections to calculate the seismic response of the pier. The results showed that the piers had a plastic deformation under the large earthquake.
