| 中文摘要: |
| 结合双塔单索面预应力混凝土斜拉桥的结构特点和荷载情况，利用有限元软件ANSYS建立全桥有限元模型，给出了有限元仿真模型命令流；采用非线性静态增量有限元分析，得到了荷载-位移曲线，进而求得了该桥的极限承载力。模拟结果能为实际双塔单索面PC斜拉桥的塑性极限分析提供参考价值。 |
| 英文摘要: |
| Combined with the structural characteristics and load situation of the double pylon single cable plane prestressed concrete cable-stayed bridge, the finite element model of the whole bridge is established by using the finite element software ANSYS, and the finite element simulation model command flow is given. The load displacement curve is obtained by nonlinear static incremental finite element analysis, and the ultimate bearing capacity of the bridge is further obtained. The simulation results can actually provide reference value for the plastic limit analysis of double pylon single cable plane PC cable-stayed bridge. |
