| 摘 要： | 采用软件ABAQUS对钢筋混凝土梁进行有限元模拟,即可获取梁的荷载-位移骨架曲线。将试验结果和模拟结果进行对比,结果表明,有限元可以较准确地模拟试验情况。然后同样采用软件ABAQUS来模拟146根梁,并获取该批梁的弯矩-转角骨架曲线。将曲线按照不同因素进行分类,并由这些曲线得出梁的性能参数:塑性转角限值。塑性转角限值能为梁的性能评估提供定量的参考指标。

| Abstract: | The software ABAQUS is used to perform the finite element simulation of RC beam to obtain the load-displacement skeleton curves of the beams. Comparing experimental results and simulation results, the results show that the finite element simulation can simulate the test situation accurately. Then, the software ABAQUS is also employed to simulate 146 beams, and we obtained the moment-rotation skeleton curves of the beams. Based on different factors, the curves are classified. The performance parameters of beams, i.e., the plastic rotation limits, are obtained from the skeleton curves. Plastic rotation limits can give quantitative reference index for performance evaluation of beam. |
