Seismic Analysis of RC Frame with the Variation of Position of Soft Storey

Vikram Singh Kushwah, Ravi Dwivedi

Uncertainties involved and behavior studies are vital for all civil engineering structures. Many buildings in the present scenario have irregular configurations both in plan and elevation. The objective of the paper is to carry out Equivalent static analysis of vertically irregular RC building frames in which Stiffness irregularity was considered for different stories at a time. These irregularities are provided as per clause 7.1 of IS 1893 (part1) 2002 code. According to our observation in case of displacement for all the position of soft storey excluded ground position, top 3 storey positions for soft storey should be safer as compare to middle storey position of soft storey. In case of maximum stresses in column for all positions of soft storey excluded ground storey give same result (approx. ) except 3rd position of soft storey. So position soft storey at 3rd is most unsafe for structure in case of stresses in column. In case of maximum stresses in beam for all positions of soft storey excluded ground storey if middle storeys of structure are soft than beams are more stressed as compare to position at top and bottom storeys. In case of maximum shear force in beam for all positions of soft storey excluded ground storey give same result (approx. ) except 1st position of soft storey. So position of soft storey at 1st is most unsafe for structure in case of shear force in beam. In case of storey drift for all positions of soft storey excluded ground storey give same result (approx. ) except 1st position of soft storey. So position of soft storey at 1st is most unsafe for structure in case of storey drift. For all the cases displacement, stresses, shear force and storey drift we found that top 3 positions in the stiffness irregular structure are most safer position of the soft storey in the structure. Soft computing tool and commercial software staad. pro V8i (select series 5) is used for modeling and analysis.
