The analysis of a Precast and cast-in-situ building. It’s structural system to determine the deformations and
forces induced by applied lateral loads. The precast building system includes precast hollow core slab, precast beam and
columns. The cast-in-situ building system includes precast slab, beam and columns. Different configuration of precast
and cast-in-situ slab, beam and columns are studied. A regular building with G+12 story height is considered. In Precast
and cast-in-situ building is considering dead load, live load, seismic forces there is a range of methods from a linear
analysis to a sophisticated nonlinear analysis depending on the purpose of the analysis in the design process. In this
paper a residential G+12 RC frame building is analysed by the linear analysis approaches of Equivalent Static Lateral
Force and Seismic coefficient methods using ETABS Ultimate 2016 software as per the IS- 1893-2002-Part-1. These
analysis are carried out by considering different seismic zones, medium soil type for all zones and for zone III using
SMRF frame type and for those of the rest zones using OMRF frame. Different parameter like base shear and
displacements are plotted in order to compare the results of the static analysis.
