Comparative Seismic Performance of RCC Beam with Rebar and Post Tensioned PSC Beam Using LRPC Strands with M35 Grade on Hard Soil

India has been identified among the most densely populated countries in the world, as per recent statistics. A severe shortage of urban land has been experienced due to this high population density. To ensure maximum spatial efficiency, buildings with aesthetic appeal have been engineered using RCC technology. In recent constructions, the advantages of Prestressed Concrete (PSC)—including lower material usage and higher structural strength—have not been fully considered. The substitution of RCC with PSC, while maintaining stability, has been regarded as the principal challenge. A systematic review of literature focusing on PSC implementation and techniques was undertaken in this dissertation. The gap in the research field was noted, as no analytical study has been reported involving post tensioned PSC beams with LRPC strand cables. Multiple simulation cases were performed using advanced structural analysis software for a commercial building model. Different structural cases with PSC beams at various floor levels were analyzed and later optimized into categories ranging from PSC-LRPC-B to PSC-LRPC-M. These optimized cases were subsequently compared against a standard RCC structure labeled RCC-REBAR-A. Key performance indicators such as beam deflection, shear force, bending moment, and total base shear under seismic effects were carefully assessed. Limiting capacities of beam resistance were investigated using these parameters and thoroughly examined. In a G+10 residential building scenario, considerable reductions in beam size were achieved using optimized PSC members. Cross sectional areas of beams were reduced by a minimum of 11.11% and a maximum of 78.79%, depending on the floor level. Finally, economic benefits were realized, as the reduction in member sizes due to PSC implementation was found to correlate with overall cost savings.
