Abstract

Now adays, due to architectural and structural requirements, complicated tall and slender buildings with various corner configurations and cross-sectional shapes are emerged, which are difficult to design using the existing wind load standards as well as using available software packages. For such conditions, an experimental study is the best solution to develop new standards and solve such design limitations. In this study a total of five rigid plywood models of equal height are prepared at a scale of 1:100, the principal model is a rectangular building with the geometry of B*D*H, 200mm*300mm*500mm and other models are vertically chamfered edges as B/8, B/4, 3B/8, and B/2. In properly designed open rectangular boundary layer wind tunnel with 2m*2m*15m simulation section at IIT Roorkee, India. The model is placed on the top floor and the mean wind velocity profile of approaching flow 9.61m/sec corresponding to terrain Category-II is allowed to pass through the circuit and various digital signal readings are taken at various wind incidences then converted to forces, moment, coefficients and results are compared with existing codes. As vertical chamfering size increases, twisting and torsional moment increases, drag force coefficient and lift-force coefficient increase due to the slenderness of the chamfered building compared with the principal building.
