Probabilistic Seismic Capacity Model for High Pier of CFST Composite Column

摘要

摘要: 为评估钢管混凝土叠合柱高墩的抗震性能,以曲率为性能指标,采用拉丁超立方抽样方法,对截面样本偏心受压进行了全过程数值模拟.根据破坏形态,将叠合柱截面损伤划分为轻微损伤、中等损伤、严重损伤和完全损伤4种极限状态并进行量化.将曲率指标的统计特征值与轴力进行三次多项式回归分析,建立了以轴力为变量的钢管混凝土叠合柱高墩的概率抗震能力模型.结果表明:以外围箍筋约束混凝土破坏为分界,叠合柱分别表现出钢筋混凝土和钢管混凝土的破坏特征;不同轴力作用下4种极限损伤状态的曲率指标均服从对数正态分布,其均值随轴力增大而减小.

Abstract: In order to assess the seismic performances of high pier of concrete-filled steel tube (CFST) composite column, curvature was chosen as the performance indicator. The whole eccentric compression process for section samples of CFST composite column was simulated by the Latin hypercube sampling (LHS) and the numerical analysis method. Based on damage patterns, 4 limit states of slight damage, moderate damage, severe damage and complete damage were defined and quantified. Cubic polynomial regression analyses for statistical characteristic values of curvature indicator as a function of axial force were carried out, and a probabilistic seismic capacity model for high pier of CFST composite column with axial force as the variable was built. The results show that the damage characteristics of reinforced concrete (RC) and CFST are shown by the dividing line of outer confined concrete damage. Curvature indicators of the4 damage limit states under different axial forces obey lognormal distributions, and their mean values decrease with the increase of axial force.
