Some stiffness matrices of special elements such as rubber bearings and components with field are derived from primary - secondary and inverse transform in structural matrix analysis. then, seismic response analytical models and non - isolated continuous rigid frame bridges are set up, while considering the interaction of soil - pile - structure and traveling wave effect simultaneously. finally, the seismic time history response of the two models is calculated by means of the finite element method, and the results show that the isolated bridge posses powerful earthquake resistance
首先論述了公路大跨徑橋梁的地震反應分析方法，其中包括樁-土-結構相互作用、行波效應等因素對結構物的影響；其次，利用結構矩陣分析中的主從變換和逆步變換，推演了幾個特殊單元的剛度矩陣，包括橡膠隔震層單元和帶剛域構件單元；最後，考慮樁-土-結構相互作用和行波效應的結合，分別建立隔震與非隔震連續剛構橋地震反應分析模型，通過有限元法對兩種結構進行時程分析，結果表明：隔震層上部結構的地震加速度反應、位移反應均明顯減小，這說明隔震的連續剛構橋具有很好的抗震能力。 -
