摘要
为了研究混凝土与剪力连接件的破坏形式及剪力连接件的极限抗剪强度,根据某实际钢-混组合桥梁结构,设计了钢-混组合梁剪力连接件试样,并进行极限抗剪强度试验,得到了剪力连接件的破坏形式和极限抗剪强度,且拟合得到荷载-滑移曲线,同时用非线性有限元模型进行仿真计算。结果表明:采用非线性有限元法得到的计算值与试验值相当吻合。
In order to study the failure modes of structural concrete and shear connector in reality and ultimate shear strength of shear connector,aprototype of shear connector was designed based on an actual structure of steel-concrete composite beam.Test on ultimate shear strength was carried out,and the failure modes of shear connector were obtained.A load-slip curve was gained,and nonlinear finite element model was applied to conduct the simulation.The results show that the value acquired by the simulation matches the test result perfectly.
