Examination of The Core as A Rigidity Center in High-Rise Buildings

Abstract

The visibility and number of high-rise buildings, which have a direct impact on shaping the texture and identity of the city in which they are located, are increasing day by day. While developing technology, new construction techniques and high-strength building materials make it possible to increase the height of the building, each increase in height occurs difficulties and requires more engineering problems to be solved. When the distribution of loads acting on high-rise buildings and their effects on the structure are examined, it is seen that the core is designed as a center of rigidity in the structure to provide inertia against horizontal loads. In order to make the core design of the building effective and efficient, it will be a proper and correct approach to understand the center of rigidity function of the core to design and implement it from this point of view. This study aims to examine the core, which plays a primary role in providing inertia against horizontal loads acting on high-rise buildings, as a center of rigidity. First of all, the loads that are effective in the design were explained. It has been stated that the horizontal loads acting on the structure cause bending, shear and torsion. The interaction of wind load, which is a more critical load especially in high-rise buildings, with the building is emphasized. In order to facilitate the understanding of the core as the center of rigidity in high-rise buildings, its place in the structural system hierarchy was defined. It has been seen that core designing is a necessity in order to provide inertia against horizontal loads in high-rise buildings that becomes independent from its surroundings as the height and the loads acting on the structure increase. It has been seen that besides the core is designed as a service core within the building, the building shell is designed as a core also.
