Abstract— At present, fast-paced urbanization together with land unavailability in major cities has caused the extensive erection of tall buildings. One of the major concerns in the case of these structures is seismic safety, especially when they are located in regions that often suffer from earthquakes. While the traditional practice of using reinforced concrete (RCC) frames is a common one in construction, it tends to contribute to greater lateral displacements and storey drifts during seismic activity. Moreover, the use of the monolithic construction system with aluminum formwork has established itself as an emerging technology in the construction industry, attracting the interest of many engineers and architects because of its structural performance, speed of construction, and economy. Reinforced concrete walls and slabs in these systems are cast together, giving the walls the role of primary gravity and lateral load-resisting elements. The main focus of this review paper is to provide an all-encompassing evaluation of the previously conducted studies dealing with the seismic performance of monolithic high-rise buildings as compared to conventional RCC framed structures. The research work spans the analytical, numerical, and experimental approaches to delineate the factors such as storey displacement, storey drift, storey shear, base shear, stiffness, and overall stability of the structure that have been singled out for investigation. Shear wall configuration, wall thickness, openings, and building height effects are also part of the discussion. Monolithic structural systems are found to be superior in terms of seismic performance, material consumption and cost-effective through the literature review thus they can be considered a very good option for sustainable high-rise construction.
