Abstract
Ductile design and detailing provisions were revised in 2016 by the Bureau of Indian Standards. It introduced Strong Column Weak Beam Provision (SCWB) for beam-column joint. In this paper, an attempt is done to investigate the influence of SCWB provision on the Longitudinal Rebar Quantity (LRQ) of typical columns i.e. Corner Column, Edge Column, and Middle Column on seismic Zones III, IV, and V for six-story buildings. Story-wise variation reached a maximum from 100% to 200% in the 4th and 5th story whereas overall variation was observed from around 50% to 80% in LRQ of the column while considering SCWB over the conventional technique of column design. Finally, the study concludes that the requirement for design strength ratio i.e. Beam column capacity ratio ( 1.4 c b MM) has resulted in excessive quantity of rebar and thereby increasing its cost specifically for the residential buildings and apartments of smaller heights.
