3.3 Test cases

46 Chapter 3

A 2 × 2 array of high-rise buildings placed in close proximity is studied. The four buildings are identical with length (L) and breadth (B) equal to 20 m and height (H) equal to 90 m. The street passage width (w) between the buildings is 3 m. Details of the building corner modifications for the different test cases are given in Table 3.3. Note that the building corner modifications are applied to all the edges of the facades and roofs of the buildings. Fig. 3.4 shows the different shapes of the building corner modifications: (a) sharp, (b) chamfered, and (c) rounded. Note that the values are normalized with the building length, B. The building with sharp edges is selected as the reference case.
