Concrete parameters.

fcu (MPa)	Ec (MPa)	ν	ft,r (MPa)	Dilation angel	Eccentricity	fb0/fc0	K	Viscosity parameter
35.1	3.1 × 10^4	0.2	2.61	30°	0.1	1.16	2/3	0.002

Note. f_cu denotes the cubic compressive of concrete, and E_c, f_b0, f_c0, and f_t,r are the elastic modulus, uniaxial compressive strength, biaxial compressive strength, and uniaxial tensile strength of concrete, respectively; K is the constant stress ratio; ν is the poison’s ratio.
