Abstract

As the demand for multistory buildings rises, so do the need for structural systems that can withstand dynamic loads like earthquakes, wind, and vibration. Reinforced Cement Concrete (RCC) deep beams and Post-Tensioned (PT) deep beams are among the structural members that have received widespread interest for their unique structural properties and performance benefits. This review paper compares the performance of RCC deep beam structure with PT beam structure of multistory buildings under dynamic loading condition. The basic characteristics of both beam systems, different dynamic loads applied to buildings and important performance parameters as the load carrying capacity, deflection, stiffness, ductility, energy dissipation, crack control, serviceability and durability are discussed. The extensive study of the latest literature has shown that the PT beams have a higher load carrying capacity, less deflection, better crack resistance and high structural efficiency, whereas the RCC deep beams are high in stiffness, shear resistance and simpler to construct. The study summarizes the benefits, drawbacks and practical use of both systems and suggests possible future research to enhance structural performance and resilience under dynamic loading.
