EARTHQUAKE RESISTANT DESIGN OF LOW-RISE OPEN GROUND STOREY FRAMED BUILDING
Present study RC framed building (G+10) with open ground storey located in Seismic Zone- II, III, IV and V is considered. The main objective of present study is the study of strengthing performance of Open ground storey(OGS) buildings according to various cases such as: (a) bare frame building (b)building with uniform infill in all storey (c) building with OGS (d) OGS with stiffer column (e) OGS with corner shear wall (f) OGS with corner cross bracing (g) OGS with composite columns. The separate models were generated using commercial software ETABS. Infill stiffness was modeled using an equivalent diagonal strut approach. Parametric studies on displacement, storey drift, shear force, bending moment and base shear have been carried out using equivalent static analysis to investigate the influence of this parameter on the behavior of building with OGS. Keywords - stiffness, infill wall, equivalent diagonal strut, strengthing of OGS building, seismic analysis
