| 中文摘要: |
| 应用平面非线性有限元对叠合框架进行了全过程分析，考虑了二阶段成型二次受力的特性和混凝土受拉应力-应变曲线的下降段，使用了Liu等人模式的混凝土破坏准则，编制了Fortran程序，并通过框架实验验证了计算方法和程序计算的可靠性． |
| 英文摘要: |
| In this paper, the whole process of the composite frames was analyzed by means of the plane nonlinear finite element. Then the characteristics of two-stage casting and two-stage loading were considered, and the descending partition intensive stress and strain curve of the concrete were adopted. Also Liu's et al concrete destruction criterion were used and the fortran program was written. Finally, the teliability of the computation and the calculation of the program was verified by testing the composite frames. |
