考虑到材料的非线性和实际连接的非线性，如桥墩、支座、碰撞和抗震螺栓等，分别用弹塑性纤维梁柱单元、滑动支座单元、接触单元和弹簧单元模拟，建立了非线性时间-本文以邢庄立交桥工程中的一座曲线梁桥为例，根据抗震设计理念，基于变形和多重破坏准则，利用该模型进行了结构在设计地震和大震作用下的非线性时程分析和抗震性能评价。
Considering nonlinear properties of material and connection in practice at length such as pier,bearing,pounding and anti-seismic bolt simulated by elasto-plastic fiber beam-column element,sliding bearing element,contact element and stiffen spring element respectively,the model is built up for nonlinear time-history analysis by taking an example of a curved beam bridge in Xingzhuang interchange bridge engineering.In the light of seismic resistant design conception based on deformation and multi-failure criteria,the nonlinear time history analyses and estimations of seismic performance are carried out under design and severe earthquake by using this model.
