The collapse characteristics of a single-layer shallow latticed dome under vertical dynamic excitation is investigated from the point of view of the absorbed energy. Both static and dynamic analyses are Performed taking into account the geometrical and material nonlinearities. By comparing the collapse characteristics under the dynamic excitation and the static distributed loads which are proportional to vibration modes, it is shown that the absorbed energies at the collapse state under both static and dynamic excitations are limited, and that the maximum absorbed energies are different with different vibration modes. This latter is a particular characteristic for the latticed dome which is distinguished from that for the plate-type space frame.
