The purpose of this papar is to present in the most reasonable way the calculation method of wind pressure distribution on the wall surface of the building having the rectangular plan, which is most prevalent among high rise buildings, subjected to a uniform wind of arbitrary direction, and the interference between two buildings standing in line so as to estimate their favorable clearance. The theoretical results as obtained from two-dimensional potential theory on the assumption of dead water domain behind the building are as follows. (1) The stagnation point on the wall surface of the building as calculated by this method is in fair agreement with the experiments in the wind tunnel. (2) The wind pressure distribution as calculated by this method, which was derived from Lamb's Hydrodynamics, as well as those calculated separately from the stagnation point by means of Eqs. (22) and (23) concerning bent plates of Report (Part 3) are fairly confirmed as to their worthiness by the above experiment. (3) The free vortex layer starting from the edge of the building can be theoretically calculated, showing fairly good agreement with experimental results. (4) It is desirable that tall buildings standing in line should be separated from each other by more than 5 times their width, in order to eliminate their interference theoretically.
