Comparison of Tall Building G+30 Based on Shear Wall System and Dual system

Abstract

The construction of high-rise buildings has been significantly affected by the growth in urban population and the scarcity of available land. With an increase in building height, lateral loads significantly impact the design. When designing tall buildings, safety and minimal damage should come first so that they can withstand lateral stresses. The structure should have enough lateral strength, lateral stiffness, and ductility to achieve these requirements. Designers may decide to focus on shear wall systems or moment-resisting frame systems among the many structural systems. Examining and monitoring how these systems behave when there is a seismic influence is crucial. In the present study, seismic response of structural system at different seismic zones was analyzed. The seismic reaction was quantified in terms of time, the largest story displacement, largest story drift, required amount of steel and concrete. Regardless of the building height and seismic zones, results showed that a shear wall system was more effective in terms of cost and lateral load resistance. The goal of the present study was to compare the seismic behavior of two bare frame systems and assess the working of shear walls work with moment-resisting frames. Shear walls and bare frames are combined in the first model, while shear walls are absent in the second model and are analyzed statically and dynamically using ETABS 2020 software.
