| 中文摘要: |
| 基于ABAQUS有限元数值模拟结果，探讨增强型混凝土永久模板—钢构架混凝土短柱和现浇钢构架混凝土短柱、现浇RC短柱的轴压力学性能，得出结论:增强型混凝土永久模板-钢构架混凝土短柱在轴压破坏过程中，主筋应变明显滞后于现浇RC短柱，承载力有较大幅度提高，增强型混凝土薄板有效参与工作；给出了该类型短柱的轴压承载力计算公式。 |
| 英文摘要: |
| Based on the finite element simulation results of ABAQUS, the axial compressive properties of reinforced concrete permanent formwork-steel frame concrete short column, cast-in-situ steel frame concrete short column and cast-in-situ RC short column were investigated. It is concluded that in the process of axial compression failure of reinforced concrete permanent formwork steel frame concrete short columns, the strain of main reinforcement obviously lags behind that of cast-in-place RC short columns, the bearing capacity is greatly improved, and the reinforced concrete thin plates effectively participate in the work. The calculation formula of the bearing capacity of the short columns under axial compression is given. |
