Abstract The mean interference effects between two rectangular buildings located in close proximity in a geometrical configuration of ‘L’ and ‘T’ plan shape are studied through wind tunnel test on 1:300 scale rigid models. The mean surface pressure distributions on all the walls of two buildings located in close proximity as well as in an isolated position are measured over an extended range of wind directions. The mean responses of pair of buildings namely, block-1 and block-2 subjected to interference effects are evaluated using experimentally obtained wind loads and, subsequently compared it, with the responses of a similar building in an isolated position. Effectiveness of upstream building location and wind orientation in changing the mean wind pressure distributions and responses of upstream and downstream building are also assessed. At wind incidence angle of 0°, presence of upstream block-1 reduces the mean along-wind displacement of block-2 of ‘L’ and ‘T’ shape arrangements up to 25% and 71% respectively as compared to that of corresponding block in an isolated position. However, the presence of upstream block-1 increases the maximum mean torque on block-2 of ‘L’ and ‘T’ shape arrangement up to 28%, and up to 88% respectively as compared to maximum mean torque developed on a similar block in an isolated position.
