摘要
采用ABAQUS有限元软件,建立了10个不同配筋率的桥墩模型,进行了弹塑性时程分析,得到了桥墩振动特性、墩顶位移时程曲线及墩底剪力时程曲线,并比较分析了不同模型在地震动作用下的抗震性能,确定了纵筋率、配箍率等参数对桥墩抗震性能的影响规律。
The paper adopts ABAQUS finite element software,establishes the bridge models with various reinforcement percentage,undertakes the elastic-plastic time-history analysis,concludes the pier vibration features,time-history curve of the pier top displacement,and time-history curve of the pier bottom shearing,compares the seismic performance under the earthquake effect,and identifies the parameter including the longitudinal reinforcement ratio and reinforcement percentage on the seismic performance of the bridge piers.
