Seismic performance of precast steel reinforced concrete building

Precast Steel Reinforced Concrete (PSRC) structural frame systems for moment-resisting, comprised of Prefabricated Steel (S) girders and Precast Reinforced Cement Concrete (RCC) columns. This structural system has the advantage of inherent stiffness and damping during a seismic event. PSRC moment-resisting frame system is also known for its construction efficiency, lightweight and low-cost. Earlier investigations have shown PSRC systems useful in designing and constructing the buildings while maintaining ample strength and high ductility during seismic incidents. Despite much previous research on it, the use of the PSRC structural system in India is still limited. Previous studies have accepted a vital need to review thorough structural systems using experiment and analytical studies-to validate the understanding collected till date and act as evidence of concept for the PSRC moment-resisting frame system. This paper aims to facilitate more recognition and use of the PSRC structural system as a feasible choice to traditional RCC lateral resisting systems. Two structures are studied to evaluate low-rise PSRC and RCC structures’ performance during maximum considered earthquake events. These consist of typical steel beams and Precast R.C. columns frame buildings. Four-story PSRC buildings are designed according to Indian Codes of practice. Design columns under provisions of Indian reinforced concrete structures code, and beams are designed according to Indian steel construction code. The comparative studies for the two buildings are presented.
