In general, parameters such as member slenderness, rise-to-span ratio, and support conditions determine the global stability of single-layer reticulated domes. The effect of member connectivity on the global and local stability of reticulated domes is usually not considered, even though they play a vital role. Hence, this paper examines the global stability of single-layer reticulated dome configurations based on the valences of vertices, edges, and faces. These valences are derived from the interrelation between the elements within a configuration. Valency is the number of specified elements connected to a different element. The valency plays a vital role in determining a reticulated dome's global stability as the interconnections ensure the smooth flow of load from the applied location to the support. Hence, the global stability of different single-layer configurations with different valences of vertices, edges, and faces is examined with different loading and support conditions. Different valences for selected dome configurations are calculated during the initial stage. Then the global stability of the dome configurations under different loading and support conditions is analyzed. The relation between the valency and the stability of dome configurations is analyzed to identify the stable dome configurations under various load conditions. Valency information helps to recognize the type of failure in the domes and reduces the probability of failure by altering the data to obtain an efficient configuration.
