Abstract. In the modern civil engineering design, especially in the field of machine foundations, the dynamic actions in the form of the impulse load that is short-term, high intensity loads are very frequent. When an acting force, during a short time interval remains constant, the impulse is of a rectangular form, as opposed to the trapezoid, triangular, parabolic and sinusoid form, with defined time of increase and decrease of the load. This paper considers the influence of the form of the impact impulse load on the dynamic response of the foundation structure, without changing the remaining parameters.
Key words: impulse load, form of the impulse, foundation, dynamic response.

ZAVISNOST OSNOVNIH DINAMIČKIH PARAMETARA
OD POREMEĆAJNE SILE TIPA UDARNOG IMPULSA RAZLIČITE FORME
U savremenom građevinskom konstrukterstvu, posebno u oblasti temelja mašina, česti su dinamički uticaji u vidu impulsnog opterećenja odnosno kratkotrajnog opterećenja visokog inteziteta. Kada delujuća sila tokom kratkog vremenskog intervala ostaje konstantna, impuls je pravougaone forme, za razliku od trapezne, trougaone, parabolične i sinusoidne, sa definisanim vremenom rasta i opadanja opterećenja. U radu je razmatran uticaj forme udarnog opterećenja na ponašanje dinamičkog sistema temeljna konstrukcija-podloga ne menjajući ostale parametre.
