In the present study, a numerical analysis was performed for interior connections of continuous flat plate to analyze
the effect of design parameters such as column section shape, gravity load and slab span on the behavioral characteristics of the
connections. For the purpose, a computer program for nonlinear FE analysis was developed, and the validity was verified. Through
the parametric study, the variations of shear stress distribution around the connection were investigated. According to the result
of numerical analysis, as the length of the cross section of column in the direction of lateral load increases and gravity load
increases, the effective area and the maximum shear strength providing the torsional resistance decrease considerably. And as the
slab span loaded with relatively large gravity load increases, the negative moment around the connection increases and therefore
the strength of connection against unbalanced moment decreases. By considering the effect of design parameters on the strength
of the connections, the effective shear strength to calculate the torsional moment capacity of connection was proposed and the effectiveness
of the proposed shear strength was verified.
