摘要：
为了准确模拟低屈服点钢材LYP100的弹塑性地震反应,需要对材料的循环本构关系进行研究.采用16种不同加载制度对LYP100的20个试件进行试验,分析单调曲线、滞回曲线、破坏形态、延性特点等.基于Ramberg-Osgood模型对逐级加载下的循环骨架曲线进行拟合.利用试验数据标定LYP100钢材的等向强化和随动强化参数,通过ABAQUS有限元数值模拟进行参数数值的验证.结果表明,LYP100钢材表现出明显的循环硬化特征；LYP100经历过循环荷载加载以后仍具有良好的延性；采用Ramberg-Osgood模型可以较好地模拟LYP100在逐级循环加载下的骨架曲线；标定的强化模型参数,应用到ABAQUS有限元软件中时,计算结果与试验结果接近.
Abstract:
In order to simulate the earthquake response of low yield point steel, its constitutive relationship under cyclic loading needs to be studied. Twenty specimens of low
yield point steel LYP100 were tested under sixteen different loading systems. Monotonic curves, hysteretic curves, failure modes and ductility properties were analyzed. Skeleton curves under cyclic loading with strain increasing step by step were fitted based on Ramberg-Osgood model. And parameters of isotropic hardening and kinematic hardening were calibrated from test data. The calibration was then verified by finite element results simulated in ABAQUS. Results show that, LYP100 steel exhibits a large degree of cyclic hardening; LYP100 has excellent ductility even after being subjected to cyclic loading; Ramberg-Osgood model fits skeleton curves well under cyclic loading with strain increasing step by step; finite element results fit test results well when calibrated hardening parameters are input into ABAQUS.
