| Experimental study on transverse dynamic property of 32 m-span prestressed concrete girder bridge on Datong-Zhungaer railway |
| 摘要 |
| 根據(jù)大準(zhǔn)鐵路32 m預(yù)應(yīng)力混凝土梁橋的實(shí)測(cè)橫向振動(dòng)數(shù)據(jù)，綜合分析了32 m預(yù)應(yīng)力混凝土梁橋的橫向動(dòng)力性能。結(jié)果表明：32 m預(yù)應(yīng)力混凝土梁橋的橫向振動(dòng)在很大程度上是由于橋墩的振動(dòng)引起的，而橋墩橫向振動(dòng)與貨列的激勵(lì)頻率、橋墩的自振特性有關(guān)，當(dāng)墩高大于20 m時(shí)，由于其有載 |
