Review on High Rise Building with Outrigger and Belt Truss System

Abstract

Abstract: In present era there is more demand of high rise building. The growing demand for high-rise buildings brings new difficulties and comes up with new safety precautions. With increase in height of structure its rigidity reduces, making it difficult to withstand with earthquake and wind effects, hence some preventative structural systems must be used. Some of them are bracings, shear wall, outrigger system and belt truss system etc. The outrigger and belt truss system is investigated in this study since it has been found to be the most effective method for high rise buildings and skyscrapers. To prevent story drift and the rotational action of the core caused by seismic and wind forces, the external columns in an outrigger system are attached to the main inner or outer core using outrigger beams, walls, trusses etc. at various floor levels. All external columns that are situated at the peripheral are connected together with truss elements in a belt truss system. A number of studies on this subject that have been done in the past are reviewed in this paper. Reviewing research papers let us know about the conclusive results, which served as the basis for the objective of our future study. One of the best systems for controlling excessive drift and lateral displacement caused by lateral loads is the outrigger and belt truss system. By using this system, the risk of structural and non-structural damage can be reduced during small or medium lateral loads caused by either wind or earthquake load
