Abstract: Rapid urbanization leads to the development of tall structures due to less availability of land and higher growth in the population. High rise structures are more vulnerable to wind forces and at higher elevation point’s structure may acts as a dynamic sensitive structure. Various countries has provided a pseudo-static constant for the calculation of dynamic wind forces known as the gust factor. Present study aims to evaluate and compare the structural response of three structure i.e. Braced Frame, Hull-Core and Shear Wall Structures under dynamic wind loading as per five different codal provisions viz. India (IS 875 (III):2015, America (ASCE 07-10), Australia/New Zealand (AZ/NZS 1170.2:2011), Canada (NBCC 2015) and British Standards (BS EN 1991-1-1-4:2005) for different structure heights and analyzed in ETABSv.16. All the structures gives satisfactory results in Open and Rough Exposure categories. Evaluated dynamic lateral forces are compared and conclusions are made. Hull-core structure has outperformed rest of the two structures. Results are evaluated on the basis of maximum storey displacement.
