摘要
针对拉—弯复合荷载情况,建立了适用于双层刚性法兰滞回性能分析的有限元计算模型。采用位移加载方法,通过对法兰在循环荷载作用下的模拟计算,获得了法兰节点弯矩关于转角的滞回曲线。分析了滞回曲线各特征点的力学性能,表明循环荷载的幅值超过静力屈服荷载后,离中面较远的螺栓会依次退出工作。分析表明,滞回曲线的骨架曲线和静力荷载作用下的弯矩—转角曲线一致。建立了基于静力荷载结果的滞回模型,并与往复荷载下的结果进行比较分析。验证分析表明所提出的滞回模型可以较好地反映双层刚性法兰的滞回特征,而计算时间大大节约。
According to tension-bending composite loading,a FEM model was established to analyze double-rigid flange's hysteretic performance.Analysis simulating flange under cyclic loading was conducted by utilizing the displacement loading method,and the flange joint's bending-rotation hysteresis curve was obtained.After analyzing the mechanics characteristics of each key points at the hysteresis curve,it was found that the bolt far from the flange's middle surface would quit the work in turn if the amplitude of cyclic loading exceeds the static yield load.Analysis shows the hysteresis curve's skeleton curve is consistent with bending-rotation curve under static load.Based on the result of static,a hysteretic model was established,and compared with the result under cyclic loading analysis.The verification analysis shows that the hysteretic model could correctly reflect the characteristics of the double-rigid flange's hysteretic performance,and the calculation time could be saved greatly.
