The present paper investigates the dynamic response of single layered reticular domes simultaneously subjected to horizontal and vertical earthquake motions. A dome which is assigned a safety factor ranging from two to four against the limit state for dead load is analyzed dynamically to the earthquake motions of Taft, El-centro and Miyagi-oki earthquakes. The collapse acceleration that is defined as the minimum acceleration enough to cause the dome to collapse is evaluated. For the dome with a safety factor of two, three and four, the collapse accelerations are found, respectively, 167, 473 and 778 gals. Based on the results, an formula to estimate the collapse acceleration is given by using the relative displacement response spectra for earthquake motions.
