Structural Behavior Comparison on Earthquake Resistance of High-Rise Mall Building (Framed Structure,Flat Slab and PT Flat slab)

Abstract

The rate of urban population growth and the amount of available space had a significant impact on the construction of high-rise mall buildings in developing countries like the USA, UK, Australia, and Hong Kong. These high-rise mall constructions may be constructed using a variety of structural techniques. Today, RC Frame structures are often employed in constructing. Usually, these structures are employed to counteract the sizeable moments brought on by applied stresses. On the other hand, flat slab structural systems, in which the slab is directly supported by columns, have lately been adopted in many buildings because they have the advantage of greater clear floor-to-floor heights to satisfy the economical, easier form-work, quicker construction duration, and architectural needs. On the other hand, with a post-tensioned slab, the PT flat slab Structural System uses high-strength tensioned steel strands to compress the slab, maintaining the bulk of the concrete in compression. When compared to RC framed structural system, this results in a very efficient construction that minimizes partial consumption and reduces the economic span range. Three cellar+Ground+9 higher floors structural models of a high rise mall building with RC framed structure, flat slab, and PT flat slab structural system arrangement are taken into consideration in the current study. The study is completed by taking into account seismic zone II and type I soil condition, and it takes into consideration the susceptibility of purely RC framed structures, solely flat slab, and completely PT flat slab systems. The structural behavior of an RC-framed structure, a flat slab, and a PT flat slab are being compared for earthquake loads. The response spectrum approach is used to do the analysis.With the use of analytical tools, parameters such as storey displacement, storey drift, base shear, and storey shear are calculated. The findings are then compared between three structural system.
