COMPARISON OF TUBULAR, OUTRIGGER AND BRACING SYSTEM FOR STABILIZATION OF HIGH-RISE BUILDINGS

In this paper structural efficiency of tubular, outrigger and bracing systems have been analyzed. Tubular system is one of the very effective and efficient system which is widely used as a lateral load resisting system for concrete and steel tall building. In this system the lateral loads have been transferred by peripheral columns and deep spandrel beams. Another very effective system which commonly used for stabilization of high-rise building is outrigger belt truss with core shear wall. In this technique basically core shear wall is used for structural strength and outrigger is used to increase its lateral stiffness of tall and super tall buildings. Locations and number of outriggers play very important role which need to be optimized. Bracing system is another technique which used as a lateral load resistance system for tall buildings. In this system lateral loads are transferred through lateral bracing by means of tensioncompression. In this paper comparison of tubular, outrigger and latera bracing systems have been studied on a 42 story concrete building by using standard package ETABS 2016
