摘 要: 采用软件ABAQUS对一批钢筋混凝土柱试验进行有限元模拟,模拟时对混凝土和钢筋的材料本构进行设置,模拟结束后即可获取该批柱的荷载-位移骨架曲线,并将试验结果和模拟结果进行对比。然后,采用软件ABAQUS模拟不同类型的钢筋混凝土框架柱,并获取该批柱的荷载-位移骨架曲线或弯矩-转角曲线。参考基于性能设计方法,将曲线按照不同因素进行分类,并由这些曲线得出柱的塑性转角限值。研究结果表明,有限元模拟可以较准确地模拟试验情况,柱的性能参数能为柱的性能评估提供定量参考指标。

Abstract:The software ABAQUS was used to perform the finite element simulation of a group of reinforced concrete column tests, the material constitutive of concrete and reinforcement were set up in simulation. The load-displacement skeleton curves of the columns were obtained after the completion of the simulation. Test results and simulation results were compared. Then, the software ABAQUS was also used to simulate different types of reinforced concrete frame columns, and load-displacement skeleton curves or moment-rotation curves of the columns were obtained. Referenced to the performance-based design method, the curves were classified according to different factors. The performance parameters of columns including the plastic rotation limits were obtained from the curves. The results show that the finite element simulation can accurately simulate the test situation. Performance parameters can provide quantitative reference index for the column performance evaluation.

 

Key words: finite element simulation; reinforced concrete columns; load-displacement skeleton curves; plastic rotation limits
