基于纤维模型的钢筋混凝土柱滞回性能数值分析
Numerical analysis of RC columns under reversed cyclic loading based on fiber model
摘要
Abstract
Three nonlinear programs for hysteresis performances of reinforced concrete columns under cyclic loading were developed based on the fiber model with stiffness-based and flexibility-based nonlinear beam-column elements and plastic hinge model. Test results of a column under cyclic compres-sive-bending loads were compared with the numerical analysis results of three methods, validating the computational effectiveness of three methods based on fiber model. Through comparison of the simulating results, it is shown that the flexibility-based non-linear beam-column elements are superior to the stiffness-based beam-column elements and plastic hinge model in dealing with the column's behaviors in strong nonlinear phase.关键词
