Abstract:

Based on the analysis of the stress mechanism and failure mode of stud shear connectors， the differential equation of the deflection line of stud shear connectors is established based on the theory of single pile under lateral load in elastoplastic foundation. According to mechanical characteristics in different stages of the stud shear connectors， the boundary conditions are introduced， the stud shear connectors of flexural differential is analyzed， and the calculation formulas of the shear bearing capacity， shear stiffness and elastic stage at the end of the slip value of the stud shear connectorscalculation formula are put forward. The load-slip tri-fold constitutive model of stud shear connectors is established, which has the characteristics of simple mathematical form and clear physical meaning. The results show that the calculated values of shear capacity， shear stiffness， elastic end slip and ultimate slip of stud shear connectors are 85.44 kN， 64.92 kN/mm， 0.64 mm and 6.13 mm respectively and the calculated values are in good agreement with the experimental values. The three-fold line load-slip relationship curve of stud shear connectors is close to the full-curve load-slip curve fitted by Buttry and Ollgaard， and it is in good agreement with the test load-slip curve of stud shear connectors.

Key words: structural engineering, steel-concrete composite beam, stud shear connector, elastic foundation beam, shear bearing capacity, the shear stiffness
