Comparative Study of Regular and Irregular RC Structure in Different Seismic Zones and Soil Types

Abstract

The resistivity of lateral forces (Wind and Seismic loading) by any structure is very much challenging. It is also one of the reasons for the failure of the reinforced concrete (RC) structure due to its asymmetric distribution of mass, strength, stiffness, and non-uniform geometrical configurations. Knowing the effect of various soils in the construction of RC structures is essential to determine the structural performance in the presence of seismic load ahead of construction. This research aims to compare regular and irregular RC structures in different seismic zones, and soil types with the provisions suggested in IS code 1893(part1):2016 and IS 875(part3):2015 using STAAD Pro V8i. Research work calculated the critical design loading for multi-story buildings put through basic wind speeds of 50 m/s and seismic zones (II, III, IV, V). The response of a G+20 storeyed RC framed building to seismic loads is examined using Indian Standard code IS 1893(part1):2016 and wind loads using Indian Standard code IS 875(part3):2015.
