浆锚连接集束配筋装配式柱抗震性能数值模拟分析
|
摘要
通过有限元软件ABAQUS建立浆锚连接集束配筋装配式柱在循环荷载下的有限元计算模型,并将模拟计算结果与试验进行对比分析,研究装配式柱构件抗震性能,分析了轴压比、搭接长度以及搭接间距等因素对柱构件承载性能和耗能性能的影响。模拟结果表明:模拟所得滞回曲线与试验数据吻合较好,且试件均为弯曲破坏模式;随着轴压比的增加,其水平承载能力增大,但延性性能降低;随着搭接长度的增大,其承载性能和耗能性能先增加,后缓慢提升,表明适量增大搭接长度可提高构件抗震性能;而随着搭接间距的变化,各模型的承载能力变化不大,说明此因素对滞回性能影响较小。通过数值模拟分析,模拟结果可以对试验数据进行验证,并进行拓展分析,以便更全面地进行概括分析,得出结论。
By using the finite element software ABAQUS, the finite element model of cluster reinforced precast columns with grouting-anchor under cyclic loading is established. The results of simulation and test are compared and analyzed to analyze the seismic performance of precast columns. The effects of axial compression ratio, lap length and lap space on the bearing capacity and energy dissipation performance of column members are analyzed. The simulation results show that the hysteresis curve obtained by the simulation agrees well with the experimental data, and the specimens are all in bending failure mode; as the axial compression ratio increases, its horizontal bearing capacity increases, but the ductility performance decreases; as the length of the lap increases, its bearing capacity increases first, and then slowly increases, indicating that an appropriate increase in the lap length can improve its seismic performance; however, with the change of lap spacing, the seismic performance of the models does not change much, indicating that this factor has little influences on the bearing capacity. Through this numerical simulation analysis, the test data can be verified, and the test can be extended and analyzed, and a more comprehensive summary analysis can be concluded.
