摘要：
Semi-rigid connections were modeled by influence of flexible structure model, and effects of semi-rigid connections in the finite element of steel frames were analyzed. Resistance capacity of members and load effective were regarded as random variables, and the reduced stiffness matrix and equivalent fictitious loads were analyzed. The Monte Carlo simulation was used to calculate the failure probability of steel frame. The analysis results were compared under three states, which was nonlinear semi-rigid, linear semi-rigid and fully pinned separately. The results indicate that the semi-rigid connections have an important impact on reliability of steel frame, so the effects of semi-rigid connection in reliability of steel frame should not be ignored. © 2016, Editorial Board of Journal of Huazhong University of Science and Technology.
