Wind Analysis of Tall Buildings for Vertical Irregularity : A Review

Abstract

Now every day, various buildings are being built for different purposes such as residential, commercial, and industrial etc. In general, in order to stabilize these longitudinal tall structures for both loads such as gravity and lateral (wind and earthquake) loads are required to take when considering the analysis and design. In addition to this there are several types of structures or buildings having different geometry in vertical and horizontal plan in the sense regular or irregular. This paper presents detailed review on the analysis of vertically irregular structure subjected to wind loads, the failure of structure starts from the weak point or joint. This weakness is exacerbated by the uneven distribution of mass, changes in elasticity or stiffness and also changes in the vertical geometry of the structure. Properties that have objections to physical or geometric regularity are referred to as irregular structures. The present study shows a review on analysis and effects in vertical irregular structure under lateral load especially in case of wind load. Many structural software and standard codes are reviewed for the creation of all members under wind load. At the end of this paper concerns the comparison of regular building with irregular structure and describes the effects in vertical irregular structure with the help of structural behaviour such as displacement, drift, axial forces, base shear and bending moment etc.
