In an optimal design of a dome building, the outer shell with a curved shape, plays an important role in the architectural approach, bearing capacity, and the structural strength in vertical and lateral loads. In this research, the effect of the arch in domes against the wind is studied, numerically. For this purpose, domes with fixed height–diameter proportion in Type C ground and with the speed and turbulence intensity matching ASCE7 regulations are numerically simulated and the amounts of pressure coefficients (Cp < /sub>) are represented on the central line corresponding to the wind direction and the rings around the dome with different heights including 0, 25h, 0.5h, 0.75h, and h. Results indicated the great effect of arch height on Cp < /sub> and the percent of under pressure surfaces.
