Built-up steel columns with battens at regular interval along their height are suffered from compound buckling and large shear deformations under axial loads. During seismic overloads, the local instability of components prevent column sections to develop their full plastic moment carrying capacities and to allow the sufficient rotations required for expected ductility demands. In the present study, the double-channel battened members are subjected to constant axial compression and gradually increasing reversed cyclic lateral load. A specimen of double-channel battened column designed as per...

Reinforced concrete (RC) framed buildings with open-ground-storey and masonry-infilled upper stories introduces severe stiffness- and strength-type of discontinuities, which together causes significant strength and inelastic deformation demand on ground-storey columns during ground shaking leading to partial or complete collapse of the buildings as observed in several past earthquakes around the world. Hence, it is necessary to develop a simple and efficient technique to enhance the lateral strength, stiffness, and energy dissipation potential of such non-ductile RC frames. A strengthening...
