Abstract
In the present research, effect of wind load on double-arched domes with different heights of arches are examined. To this end, double-arched domes with fixed height-to-span proportions in Type C ground are numerically simulated and the amounts of Pressure Coefficient (Cp) at the central line parallel to the wind direction, and also on the rings around the domes with different heights are analyzed. Numerical results are verified with the experimental data. Results showed the effect of different variables as height of arches, failure to the junction of two arches and the connection area of two arches on Cp.
