摘要
根据隔震桥梁的设计特点 ,分别利用非线性水平和转动弹簧单元来模拟减、隔震支座和桥墩延性塑性铰的非线性性能 ,计及隔震器、减震器的作用对桥梁结构非线性弹塑性动力反应进行研究 .采用大型结构分析软件ANSYS ,结合算例分析了桥梁采用减。
In this paper, according to the behavior of seismic isolation systems for bridges, the nonlinear behavior of aseismic bearings and ductile plastic hinges of piers are taken into account by using nonlinear spring element. One design example of a bridge is presented to investigate the effect of aseismic design. When nonlinear seismic response analysis is carried out, the isolation effect is discussed.
