Abstract: The prefabricated pre-stressed reinforced concrete structures are becoming popular in various parts of the globe due to its good quality control and less erection time as compared to cast in-situ RC structure. However, in Indian construction industry use of such building systems is not gaining impetus due to hesitation of structural designers concerning its seismic safety. Although, some past analytical and experimental study conducted elsewhere indicates that the pre-stressed precast reinforced concrete (PPRC) structures can perform well under seismic loading. The improvement in seismic performance was observed due to the use of pre-stress post tensioned tendons connecting beam-column interface. In case of PPRC structure, the joints are not monolithic and hence the overall force distribution in the beam-column framing system will be different than that of monolithic reinforced concrete (MRC) frame structure. Therefore, the present work proposes a new iterative process of linear analysis to determine the internal elemental forces viz. bending moment, shear force and axial load for PPRC structure. Pre-stressed precast beams and non-pre-stressed cast-in-situ columns have been considered for 3D modelling of the building. The nonlinear moment-rotation properties for beam-column interface are obtained from monolithic beam analogy. The comparative study of linear analysis results and non-linear seismic performance of MRC structure as well as PPRC structure has been performed
