ABSTRACT
The geometrical modeling of structures has been performed using the written software by the researchers and coordinates of joints of dome have been obtained. The configurations of single layer reticular domes studied here are shown in figure 1. The form is a
spherical surface with a base diameter of 60 m, and each dome is assumed to be pin-supported at its base. Previous studies show that the responses are very different for low and high rises (Kato et al. 1997). As for the rise of domes, the half open angle φ is varied from 60 to 120 degrees, step by 15 degrees to investigate its effects to the responses. Four cases depending on the magnitude of the half open angle are studied. Figure 1 shows that the shape and the member arrangement of a rigidly jointed reticular dome simply supported at the boundary nodes. As for the boundary condition, the nodes of the outer ring are pin supported.
