Stiffness analysis of shear stud group connectors in precast concrete deck
Highlights Based on the test results, a refined finite element model was established for the push-out test of SSGCs. Parametric analysis was carried out through the finite element model, and the factors affecting the static performance of the specimen were analyzed. The stiffness of the SSGCs at the elastic stage was theoretically analyzed by using the thrust pile comprehensive stiffness method.
Abstract A refined finite element (FE) model was established to simulate the push-out test of shear stud group connectors (SSGCs). The failure phenomena and interface shear-slip curves obtained by the FE model were compared with the test results and found to be in good agreement. The verified FE model was then used in a parametric analysis, considering the concrete strength, stud diameter, stud height, stud spacings (longitudinal and transverse), strength of grouting material, and number of shear studs in a SSGC. Based on the Winkler foundation model and the comprehensive stiffness principle of thrust piles, a theoretical calculation formula for the stiffness of SSGCs was obtained, considering the concrete material, stud diameter, and number of shear studs in a SSGC. The calculation formula was verified with the test results and fitted with the FE analysis results.
