根据配筋UHPC梁中钢纤维的分布、体积掺量和受力情况,采用具有加筋特性的Solid65单元进行钢纤维模拟,考虑配筋UHPC梁受力过程分为弹性阶段、带裂缝工作阶段和破坏阶段,建立了钢纤维三折线本构模型。模拟结果与试验值吻合程度较好,表明该模拟方法精度较高。
According to the distribution of steel fiber, the volume content of steel fiber and load conditions in the actual reinforced UHPC beams, the Solid65 unit was used to simulate the steel fiber. Considering that the UHPC beam force process can be divided into three stages: elastic stage, crack working stage and destruction stage, the trilinear constitutive model of steel fiber was eatablished. The simulation results are in good agreement with the experimental values, which indicates the numerical simulation method has a high precision.
