Abstract
The influence of composite girders on the modified buckling factor for columns was investigated in both braced and unbraced frames. The composite girders' end conditions were represented as rigid and hinged . Furthermore, based on the proposed stiffness parameter, the derived formulation follows the same assumptions as the standard effective length factor (K-factor). Moreover, the suggested buckling factor equations for composite girders in braced and unbraced frames were obtained using the slope-deflection method. Concerning the unbraced frame, the proposed buckling factor of columns restrained by the composite girder improves the effective length calculation and makes for a more accurate and cost-effective design than the buckling factor of columns restrained by the steel girder. Eventually, the proposed buckling factor of columns in braced frames with the composite girder is only slightly better than the buckling factor of columns restrained by the steel girder, but it is still more accurate than the conventional solution
