3) fiber beam-column element
纤维梁单元
1.
Under the huge earthquake ground motion,fiber beam-column element is used to simulate the plastic hinge in piers,the result of nonlinear time history analysis shows that the plastic deformation and dissipative energy in the bridge using LWC in superstructure is remarkably slighter than that using NWC in superstructure.
通过对比分析,得知采用轻质混凝土和普通混凝土上部结构的全桥动力特性差异及其原因;采用纤维梁单元模拟桥墩塑性铰,分析了在大震激励下两种结构桥墩的塑性铰破坏程度与滞回耗能。
