Numerical Simulation of Static Stress-Strain Relationship and Failure Mode for Freeze-Thaw Concrete

Table 1

Static compression and split tensile data of concrete after different numbers of freezing-thaw cycles.

Number of freeze-thaw cycles	E (GPa)	fcm (MPa)	εcm (10^−6)	Ftsm (MPa)	εtsm (10^−6)
0	30.7	44.93	2150.3	2.27	67.75
25	21.6	40.10	2482.0	1.63	95.07
50	18.9	31.57	3095.0	1.22	119.1
75	10.2	19.67	4696.7	1.07	146.2

Note. E is the initial elastic modulus, f_cm is the peak stress, ε_cm is the strain at peak stress, F_tsm is the peak split tensile strength, and ε_tsm is the corresponding strain for peak split tensile strength.
