Abstract. The problem of the determination
of limit bearing capacity of beam cross section under pure bending, eccentric
tension, pure shear, as well as combined stress is considered in this paper.
The influence functions of the bending moment and axial force, as well
as the bending moment, axial and shear force on the cross section limit
bearing capacity in case of rectangular and I beam cross section are derived.

GRANIČNA ANALIZA KOMBINOVANO
NAPREGNUTIH GREDA
Ovaj rad razmatra problem utvrđivanja granične
nosivosti preseka grede pod čistim savijanjem, ekscentričnim zatezanjem,
čistim smicanjem, kao i kombinovanim naprezanjem. Izvedene su uticajne
funkcije momenta savijanja i aksijalne sile, kao i momenta savijanja, aksijalne
i sile smicanja na graničnu nosivost preseka u slučaju greda pravougaonih
i I profila.
