    Abstract. The paper proposes a non-standard approach to estimating the stochastic behavior of structural elements of buildings of large-panel housing construction and their nodes from pulsed dynamic external influences. An assessment of the reactive inertial resistance of the constructives of buildings and structures to complex kinetics in form and content is presented. A criterion has been developed for evaluating the behavior of constructives in the form of a symmetric matrix, the elements of which are moments of inertia in the coordinate system proposed by L. Euler that determines the kinetics of precession, nutation and angles of proper rotation of structural elements of buildings and structures, as well as their nodes. The calculation scheme for determining the inertia tensor for a typical reinforced concrete panel of large-panel housing construction is given. The terminology of "group theory" for engineering evaluation of the probabilistic reactive response of structural elements of buildings to external and internal impulse dynamic effects is considered. The practical significance of the study consists in the graph-analytical method proposed in the work, which makes it possible to predict the deformative behavior of the studied objects in known confidence intervals.
    Keywords: large-panel housing construction, dynamic impulse effects, vector space, moments of inertia, inertia tensor, algebraic object, graph-analytical method
