Table 1 Material parameters for concrete (reference [18])
From: Finite element analysis of reinforced concrete deep beam with large opening
Material property | Explanation |
|---|---|
E [GPa] | Young’s modulus (initial value): \( {E}_0=\left(6000-15.5{f}_{\mathrm{cu}}\right)\sqrt{f_{\mathrm{cu}}} \) |
ft [MPa] | Tensile strength: \( {f}_t=0.24{f}_{\mathrm{cu}}^{2/3} \) |
f′C [MPa] | Compressive strength: f′c = 0.80fcu |
ƐCp | Plastic strain at compression edge: Ɛcp = fc/E0 |
GF [Pa] | Fracture energy: GF = 0.000025ft |
wd [m] | Critical compressive displacement = − 0.0005 m |
μ [-] | Poisons ratio = 0.20 |
\( {r}_c^{\mathrm{lim}} \)[-] | fc reduction due to lateral tensile strain = 0.80 |
