In accordance with the foregoing two parts of the series, this paper presents the wind pressure distribution on buildings having such plans as of star type, cross type and deflected type, subjected to a uniform stream, by means of the two-dimensional potential theory. Then, on the assumption that a constant negative static pressure prevails in the dead water region behind the obstacle, the author tries to trace the free vortex layer starting from the edge of the building or the plate and find out it logically unaffected by the presence of the negative pressure in the dead water region On the wind-ward side of building, and flat or deflected plates the following conclusion may be drawn. (1) In case of the building having plans of star type, subjected to an axially symmetrical and uniform stream, the greater part of the wing is under positive pressure, and the longerthee wing is as compared the side, the stronger does the suction on the side become. (2) It may not go too far to say that the wind pressure distribution around the roofs and sides of the buidings can be inferred from those on the flat or deflected plates having the same angles of inclination, provided that the latter is modified by the suction caused by the building height, etc. (3) This calculation method is in fair agreement with experiments and exact solutions concerning flat and deflected plates by two-dimensional potential theory.
