Effect of the connecting beam stiffness on the bracing limit for reinforced concrete slender columns in single and multi-story frames

Abstract The main purpose of this paper is to study analytically the behavior slender reinforced concrete columns existing in sway and non-sway structures. studied variables were stiffness beam connected columns, bracing number bays stories structure model. stability was required limits for lateral determined using a finite element program perform buckling analysis, linear geometric nonlinear analysis different frame structural models. All results obtained compared available methods included building codes suggested by other researchers. indicated that minimum value limit, restrain column against side-sway, depends on connecting beams, stories, bays. limit decreases with increasing However, increases increase structure.
