| 摘 要： | 采用非线性有限元法,对钢筋混凝土板冲切破坏建模。提出1种模拟冲切破坏的分析程序。通过1个大比例尺的无抗剪钢筋的钢筋混凝土板的冲切破坏试验,说明该程序的有效性。通过一组参数分析,得出影响板抗冲切能力的关键因素。该程序用于模拟在伦敦帝国理工大学进行的大比例尺混合钢筋混凝土平板的冲切破坏响应。试件包括1个管状钢柱柱头和1个ACI318结构钢柱头。分析结果基本可以预估剪切柱头对抗剪承载力的贡献,并且能评估现行的钢柱头的可靠性。

| Abstract: | This paper deals with the odeling of punching shear failure in reinforced concrete slabs using nonlinear finite element analysis.An analytical procedure is presented for simulating punching failure.The procedure is validated for a large-scale reinforced concrete flat slab without shear reinforcement that failed in punching.A parametric analysis is carried out to determine the influence of the key parameters which govern the performance.The analytical procedure is then used to model the response of a large-s... |
