Construction of the models is carried out using finite element method, generalized coordinates and tools of modern computer software. Parametric resonance in a statically indeterminate frame caused by external excitations is investigated. Main instability domains of the frame are determined.enparametric excitationreduced modelreduced modeldynamic instability domainthe department building mechanicsthe department theoretical mechanicsArticle624.072
