| Analysis of earthquake response on large-span continuous frame bridge with high piers |
| 摘要 |
| 以芙蓉江特大橋?yàn)楣こ瘫尘?，采用有限元軟件ANSYS建立了大跨高墩連續(xù)剛構(gòu)橋的有樁和無(wú)樁兩種空間有限元模型，對(duì)其動(dòng)力特性和地震響應(yīng)進(jìn)行了計(jì)算分析。采用反應(yīng)譜法和時(shí)程分析法分別計(jì)算了E1地震作用下，結(jié)構(gòu)的位移響應(yīng)和內(nèi)力響應(yīng)，考慮了順橋向+豎向和橫橋向+豎向兩種工況。分 |
