Obezbeđenje lokalne duktilnosti armiranobetonskih elemenata prema evrokodu 8 – koeficijent utezanja
The design of local ductility for reinforced concrete elements by eurocode 8 - confinement effectiveness factor
Апстракт
This paper is focused on the effects of confinement of the reinforcement reinforced concrete sections, i.e. in the way that the transverse reinforcement affects the improvement of the characteristics of both the material and the affected zone of the element. The practical meaning of the confinement effectiveness factor from the expression of Eurocode 8 was explained. Size of the part of element that is effectively confined by the stirrups is estimated on examples of differently reinforced circular and square sections of the column by analysis of the three-dimensional presentation of effectively confined concrete sections. The connection between confinement effectiveness factor by Eurocode 8 and real effective concrete core is established.
