Wind-induced responses of buildings

This book presents the results of wind tunnel studies on 1:300 scaled down building models having same plan area and height but different plan shape. Total nine numbers of building models having a plan shape of square, rectangular, L-shape and T-shape are tested in the boundary layer wind tunnel. Mean, r.m.s., maximum and minimum pressure coefficients are evaluated from the measured fluctuating wind pressure records at all pressure point at wind incidence angles of 0º to 180º at an interval of 15º. Effectiveness of building model shape and wind incidence angles in changing the wind pressure distributions and peak suction is assessed. The prototype rectangular buildings as well as two rectangular buildings arranged in L-shape and T-shape are analyzed using the wind loads obtained from the wind tunnel study at wind incidence angles of 0º to 90º at an interval of 15º to obtain their mean responses. The mean responses of block-1 and block-2 of L-shape and T-shape buildings arrangement are compared with similar buildings in isolated position and the interference/shielding effects between the pairs of closely spaced buildings are investigated.
