The paper considers aspects of the reactive behavior of structural elements of large-panel housing construction. The problem of determining the position in space of the material point (center of mass) of the objects under study is solved, thus allowing us to evaluate the kinetics of the behavior of structural elements as a whole. New original calculation schemes are proposed, relative to all spatial axes, for determining dynamic reactions in the connections of structural elements under pulsed dynamic action on buildings and structures. A system of local oscillator forces balanced by inertial internal and external influences has been compiled by the method of kinetostatics. The interpretation of the behavior of structural elements of buildings using various oscillators is proposed. This interpretation made it possible, using periodic harmonics, to quantify the change in kinetic energy of structural elements as a result of their impact on each other due to external pulsed dynamic influences. An algorithm for determining dynamic reactions in the junctions of structural elements of buildings and structures has been developed and presented.
