The energy dissipation capacity of conventional concentric braced frames in multi-storeyed buildings degrades drastically under earthquake loading, due to buckling of bracings under the compression regime. Non-Buckling bracing is an innovative patented system, in which the buckling of the bracing is prevented and the energy is dissipated by plastic deformation under tension–compression cycles, with stable hysteresis. The strength and stiffness of Non-Buckling bracing can be tailored to obtain the desired level of storey drift limit and energy absorption. A single-bay ten-storey concentric braced frame with diagonal Non-Buckling bracing is chosen for studying their effect during earthquake loadings. Non-linear time history analysis was carried out using SAP2000 to study the variation of maximum base shear, roof displacement, inter-storey drift, Damage Index and stresses in various members due to the El Centro earthquake accelerogram. It is observed that Non-Buckling bracings are effective in dissipating energy and controlling inter-storey drift.
