Abstract:
Based on the theoretical basis of steel-concrete composite beam and composite frame and the analysis of main influencing factors of negative bending moment rotation capacity, authors established an approach for design of stability of composite beams in composite frames and deduced the bending moment amplitude modulation parameter for both beam-continuate and column-continuate composite frames. The corresponding computation formulae were proposed and a simplified stability design method for composite frame beams was introduced. The results show that roational stiffness is designed reasonably by redistributing internal force in plastic hinge of composite frames, and composite action and joint ductility can be used sufficiently
