Equivalent Wind Static Load Analysis on Tall Structures

Structures are classified into two types rigid and flexible, our part of the study is on tall structures which are more flexible and are susceptible to the vibrations which are caused or induced by wind forces. In the analysis and design of high rise buildings estimation of wind loads and their inter story drifts are the two important things to be considered for the reason that there should be safe living of the inhabitants. Inter storey drift can be controlled through suitable structural system. The present study involves the study of calculation of wind displacements and its inter storey drifts using equivalent static analysis for forty storey building and results are compared with respect to various wind speeds .Also analysis is carried out for static and gust pressure comparision,as well as base shear calculations. Structure is analyzed using fem analysis with wind load calculated by static method as per IS-875partIII 1987 with and without shear walls.
