摘要：

Based on the experimental results of fully bolted diaphragm-through connections composed of concrete-filled steel tubular columns and H-shaped steel beam, 3D nonlinear finite element models were established to analyze the mechanical properties of this new fully bolted diaphragm-through connection using ABAQUS. An analysis was conducted under cyclic loading. A method to estimate the bolt flip platform was presented and used to correct the hysteretic curves for the fully bolted through-diaphragm connections. The failure modes, load-drift, and stiffness degradation curves of the finite element analyses were found to be in good agreement with the tests results.
