ABSTRACT / SAŽETAK:
U radu je analizirana primena matematičkih modela Popovics, Evrokod 2 i Stojkovic za opisivanje krive napon–dilatacija 3D štampanog betona (3DPC) na osnovu dostupnih eksperimentalnih podataka. Na osnovu RMSE kriterijuma, utvrđeno je da model Stojkovic najbolje aproksimira eksperimentalne rezultate. Predložene su i funkcije zavisnosti parametara od čvrstoće betona, čime se doprinosi preciznijoj numeričkoj analizi konstrukcija izrađenih 3D štampom.
KEYWORDS / KLJUČNE REČI:
3D štampani beton, tehnologija 3D štampe, veza napon-dilatacija
