WIND EFFECT ON TALL STRUCTURE

Abstract

The design of buildings must take into consideration the lateral drift of the structure due to wind loading and any serviceability issues that may arise from this lateral movement. Modern Tall buildings designed to satisfy lateral drift requirements, still may oscillate excessively during wind storm. Sometimes these oscillations may even cause discomfort to the occupants even if it is not in a threatening position for the structural damage. So an accurate assessment of building motion is an essential prerequisite for serviceability. This report begins with a comprehensive review of the literature that covers all pertinent aspects of wind drift in buildings. Next an explanation of the procedure of analysis procedure is studied. A study is carried out in which height wise design forces are computed by analytical method (IS 875) and base shear is calculated. Due to different height of building both static and dynamic analysis is done using IS 875. This report also carries a study of difference in Base bending moment as per different international codes and standards.
