A shallow lattice dome subjected to three independent sets of step or impulse loads is investigated. Symmetric and asymmetric loading distributions are considered. The dynamic response is determined by numerical integration, and critical loads are defined by the Budiansky‐Roth criterion. Interaction curves for fixed maximum response and for snap‐through instability are obtained, and a comparison is made with previous results for static loading.
