摘要 随着型钢混凝土结构在建筑结构中的广泛运用,对型钢混凝土结构的承载能力研究就越来越重要,而扭矩荷载在建筑结构中普遍存在.基于台湾大学HSU H L的3根箱形型钢混凝土构件试验结果,利用有限元分析软件ABAQUS建立模型,对这3根型钢混凝土纯扭构件进行抗扭承载力分析,建模过程中采用内聚力黏结单元模拟型钢与混凝土之间的黏结滑移作用,使模型更接近真实状态.同时,利用试验结果对箱形型钢混凝土纯扭构件承载力计算公式进行验证,确保为工程设计提供正确的理论方法. With the steel reinforced concrete structure widely used in building structure,the research on bearing capacity of steel reinforced concrete structure becomes increasingly important.What′s more,the torque load is widespread in building structure.Based on the test results of three box-shaped steel reinforced concrete members by HSU H L of Taiwan University,this article builds models and analyzes the torsion capacity of the three steel reinforced concrete pure torsion members through finite element analysis software ABAQUS.Bond-slip effect between steel and concrete is simulated as cohesion bonding element in the modeling process to make the model close to the real state.Meanwhile,the test result proves the calculation formula of bearing capacity of box-shaped steel reinforced concrete member under pure torsion.The result provides a correct theoretical method for engineering design.
