Analysis on the effect of different bracing types and layouts on lateral drift of 30-storey steel framed building subjected to lateral forces using ANSYS

High-rise steel construction is increasing at an expanding scale and in modern construction stiffness of the structure has become paramount criteria as the building increases in height. However, the aerial threat of wind forces had become a crucial factor to affect the building stiffness. Designers...
