Abstract:In order to study the influences of stud diameter, cut-through rebar diameter, holing aperture and hole number of multi-row combined shearing force connector on the anti-shear bearing capacity and the load-slippage curve, ABAQUS software is used to establish the combined shearing force connector model to compare and validate its feasibility with the existing tests. On this basis, the multi-row combined shearing force connector model is established to carry out the parameter analysis. The result shows that the increment of hole number, holing diameter, cut-through rebar diameter and stud diameter can effectively improve the anti-shear bearing capacity of the combined shearing force connector. In which, if the hole number is below 4, there is no interaction between various holes, and the bearing capacity increases linearly with the number of holes. The diameter of cut-through rebar lower than 16 mm has little influence on the bearing capacity of combined shearing force connector. When its diameter increases from 16 mm to 20 mm, the bearing capacity of component is obviously improved. There is no relationship of linear increment between the stud diameter and bearing capacity. Based on the superposition principle the computational formula of bearing capacity for multi-row combined shearing force connector is established. The calculated values are in good agreement with the numerical calculation results.
