000010733 520__ $$2eng$$aThe objectives of this paper are to investigate the pattern of contact between angle and column in the vicinity of bolts for semi-rigid steel beam-to-column connections with bolts and angles, and propose a mechanical model for initial stiffness reduction calculation and derive a new formula to calculate initial stiffness of the connections. In this study a nonlinear separation curve in the contact between angle and column is observed and used as foundation to develop an initial stiffness formula. Results calculated using the proposed initial stiffness formula are compared with numerical results from finite element analysis and comparison shows error within ±10%. Results calculated using the proposed formula are also compared with some lab test results. The comparison with lab test results is not as good as comparison with numerical results because lab test instruments were chosen for ultimate strength measurement with large deformation and were not very accurate for small displacement as well as initial stiffness measurement.
