suction developing on their upper surface along with the pressure occurring on their lower surface (for most wind directions), which together may generate critical
uplift forces causing serious damage. The paper presents past research on wind effects on canopies of low buildings, originated mainly from atmospheric boundary
layer wind tunnel studies. Provisions for wind pressure on canopies in different wind standards and codes of practice are also reviewed. Findings of past and recent
studies are then compared with the provisions of various National Codes on wind loading on canopies. Comparisons of the experimental results with some
computational results and the provisions of wind codes and standards show significant discrepancies. Some of these differences are due to the variety of configurations
used in the previous studies, e.g. building geometry, size and slope of overhangs, canopy location on the wall(s), existence of openings, as well as roof shape
(flat, gabled or curved / arched).
