Abstract


The objective of this study is to investigate the seismic behavior of the structure having various structural configurations like OMRCF (Ordinary Moment Resisting Concrete Frames), SMRCF (Special Moment Resisting Frames) and BSF (Braced Steel Frames). A comparative study of all the types of frames will shed light on the best suited frame to be adopted for seismic loads in Indian scenario. For this purpose, a G+4 building was designed for OMRCF, SMRCF and BSF framing configurations in Seismic Zone V according to Indian codes. Tests were carried out to evaluate their structural efficiencies in terms of storey drifts, Base shear, amount of reinforcement etc. Moment frames have been widely used for seismic resisting systems due to their superior deformation and energy dissipation capacities. A moment frame consists of beams and columns, which are rigidly connected. The components of a moment frame should resist both gravity and lateral load. Lateral forces are distributed according to the flexural rigidity of each component.
