STUDY OF CRITICAL ASPECTS FOR GLAZING AND FACADE DESIGN FOR WIND LOADING

Abstract

Tall buildings are the representatives of the modern cities and they are the only options for the future because of the lack of space for spanning a building horizontally. The only way for accommodating the ever increasing population in the limited area is to span our buildings vertically. With the construction of tall buildings, the design criteria should be such that it can take up the loads acting on it. Wind load is the most important factor that needs to be considered. And moreover wind can even take a shape of disaster. Large wind pressure fluctuations can occur on the surface of a building. Due to which the structural system is imposed with large aerodynamic loads and intense localized fluctuating forces act on the facade of such structures. Hence the facades become one of the most sensitive areas to be looked into while analyzing the loads acting on different parts of the building and designing the building as a whole. This paper brings out the effect of wind on high-rise buildings with respect to varying aspect ratio. The analysis is conducted using the concepts of CFD in the software package GAMBIT-FLUENT. The average of the drag coefficient, rms value of the lift coefficient, Strouhal number and the mean base pressure coefficient on the back side of the cylinder have been evaluated and plotted.
