摘要:
为分析型钢混凝土(SRC)在低周反复荷载作用下的损伤演化过程,利用纤维模型对其进行精细模拟。分别利用位移型梁柱单元和带塑性铰的力型梁柱单元建立有限元模型,对截面上相应的混凝土、钢筋和型钢纤维定义各自的单轴本构关系。滞回曲线及损伤演化过程的计算与试验结果均吻合较好。分析表明,纤维有限元数值分析技术可以精细模拟SRC柱在低周反复作用下的损伤性能。
Abstract:
Fiber finite element model was used to analyze the damage behaviors of steel reinforced concrete(SRC)columns under low-cyclic loading tests.Two finite element models were compared with each other,which were the displacement-based beam-column elements model and force-based beam-column element model.The material constitutive relationships of concrete,reinforcement and steel were defined respectively by their corresponding fibers of the cross section.The calculated results of hysteretic curves and damage evolution curves are both in good agreement with the test results.This analytical work shows that the seismic damage behavior of SRC column could be simulated tenuously by the fiber FEM.
