| 64 m下承式鋼桁結(jié)合梁的動(dòng)力性能試驗(yàn)研究(49 卷) |
| 英文標(biāo)題 |
| Experimental study on dynamic performance of 64-m span steel truss composite girder through bridge |
| 摘要 |
| 下承式鋼桁結(jié)合梁剛度大，可采用有砟橋面，行車噪聲小，乘客舒適度高。通過測(cè)試64 m下承式鋼桁結(jié)合梁的自振特性和動(dòng)力響應(yīng)測(cè)試，分析在動(dòng)載作用下橋梁結(jié)構(gòu)的工作狀態(tài)，判斷列車通過時(shí)橋梁的安全性。 |
