COMPARATIVE ANALYTICAL INVESTIGATION OF 2D STEEL FRAMES SUBJECTED TO LATERAL LOAD USING STEEL CABLE BRACING

Steel structures can be strengthened against lateral loads in different ways. The most common and efficient way of strengthening steel structures is by providing bracing systems to them. From the past studies, it's clear that braced frames or bracing systems helps in maintaining more structural stability or gives better resistance when lateral loads are applied. The efficiency of the braced frame when compared with unbraced frames depends upon the selection of bracing system. The rapid development in construction industry globally demands for new bracing systems. So, this paper deals with the analytical study of a new and innovative steel cable bracing connection for strengthening and for reducing the effect of lateral load acting to the structure. For this purpose, G+11 multi storied 2D steel frames were considered. The 2D steel frames considered for this purpose are same in dimension but differentiable by their bracing systems provided, which includes Unbraced, Single diagonal braced, X braced, V braced, Inverted V braced, K braced, Knee braced and steel cable braced frames. ANSYS Mechanical APDL 15.0 software package have been used for getting analytical values like displacement, bending moment and shear force. Design and load calculations had been done as per Indian Standard codes.
