摘要: 基于有限元仿真分析技术和混凝土本构理论,提出了有限元仿真分析和实物验证试验相结合研究剪力 连接件的新方法.将此方法用于3类共7个子类新型剪力连接件的全过程受力分析,并将有限元分析结果和模 型试验结果进行对比,证实了这一方法的有效性和准确性,使得通过有限元仿真分析和实物验证试验相结合研 究多种剪力连接件的受力特性成为可能.Abstract: Based on the finite elementmethod (FEM) and the constitutive model of concrete, a method of analyzing the mechanical behavior of shear connectors was put forward. This method includes FEM simulation analyses and verification experiments, but only few experiments must be carried ou.t The method was used to analyze the mechanical behavior of new type shear connectors classified into three types and seven sub-types. The validity of the proposed method has been demonstrated through the comparison between the simulated and experimental results to be able to investigate themechanicalbehaviors ofmany kinds of shear connectorswith themethod.
