PERFORMANCE OF DIAGONALS IN HIGH RISE STEEL STRUCTURES

In future one will continue to construct buildings interesting rather than monotonous, however this has to be done at the cost of poor performance of buildings. The braced system will give more flexibility in architectural design and it is structurally more efficient compared to other normal framing systems and lateral load resisting systems like shear wall, core wall systems, and tubular framing system and outrigger structural systems. In this study the behaviour of the high rise steel structure with and without braces and different type of braces like X-type, A-type, V-type and single diagonal type brace are studied by comparing results of different models. Dynamic Analysis by response spectrum is carried out using ETABS 2016. The results are discussed through various parameters like displacement, storey drift, storey stiffness etc
