| Study on vibration-isolation effect of E-type steel bearing of railway simply-supported girder bridge |
| 摘要 |
| 以某鐵路不同墩高的8跨簡支梁橋?yàn)槔?，基于大型有限元分析程序SAP2000，分別建立了各跨簡支梁橋的未隔震模型及采用E型鋼阻尼支座進(jìn)行減隔震的計(jì)算模型。采用了七條實(shí)際地震波作為激勵(lì)進(jìn)行了動(dòng)力時(shí)程響應(yīng)計(jì)算并進(jìn)行統(tǒng)計(jì)對比分析。分析結(jié)果表明，對于不同墩高的橋墩，E型鋼阻尼 |
