Research on 3D FEM Nonlinear SimulationM ethod for Shear Connectors

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.
