Behaviour of multistoried composite structures with different wind velocities and structure heights

Abstract

In India concrete and rolled steel sections are used in construction activities, steel composites are often being used based on their advantages in heavy structure like multistoried structures and also in offshore structures. In this study we tried four composite structure models G+5, G+10, G+20, G+30 are considering with varying wind velocities 33,39,44,47,50,55m/s, as per IS875-part-3 and structure foundation depth is considered 2m below foundation level and the base conditions are fixed at the bottom or at the supports/footings. The structures modeled in ETABS structural analysis and design software by considering various loads and load combinations by their relative occurrence are considered the material properties considered are M30 concrete grade & FE415 reinforcing steel.
