| 摘 要： | 为了分析轴压比对预应力混凝土扁梁框架内节点抗震性能的影响,运用ANSYS软件,模拟了单调荷载作用下预应力混凝土扁梁框架内节点的荷载-位移曲线,并与相应的试验结果进行比较分析。在有限元模拟试验的扁梁框架内节点的基础上,用ANSYS软件模拟了未做过试验的不同轴压比下的扁梁框架内节点荷载-位移曲线,模拟结果表明,轴压比的增大在一定程度上可以提高试件的承载力,但是太大的轴压比则会使试件的延性不足,反而会对抗震不利。

| Abstract: | To analyze the impact of axial compression ratio on the seismic behavior of inner joints of prestressed concrete flat-beam frame,load-displacement curves of inner joints of prestressed concrete flat-beam frame under laterally monotonic load were simulated by ANSYS software,and the analysis results were compared with the experimental results.Based on the finite element analysis results,the load-displacement curves of inner joints of prestessed concrete flat-beam frame with different axial compression ratios ... |
