The document contains tables for the design of reinforced concrete structures according to EC2 (Eurocode 2). It includes tables for dimensioning rectangular cross-sections, selection of reinforcement for slabs and walls (rebar diameter and area), and selection of reinforcement for beams. The tables provide values for parameters including strain, force, and dimensions for use in structural design calculations.

PRIJENOS OPTEREĆENJA S PLOČE NOSIVE U DVA SMJERA NA GREDE I ZIDOVE
Ležajni pritisak pravokutnih ploča na grede ili zidove kontinuirano je promjenljiv oblika parabole.
Za potrebe prakse ovo opterećenje zamjenjuje se trapeznim (za dužu stranu ploče) ili trokutnim (za
kraću stranu ploče). Grede se radi jednostavnosti proračuna nadalje mogu proračunavati sa
zamjenjujućim jednolikim kontinuiranim opterećenjem (prema izrazima danim na slici). Ovim
zamjenjujućim opterećenjem dobiju se isti momenti savijanja, ali oko 25% veće poprečne sile.
