relationships. The ultimate failure load observed in the test [ 7.29 ] was
1432.3 kN at a deflection of 177.8 mm, while the ultimate failure load pre-
dicted from the finite element analysis was 1424.9 kN at a deflection of
177.1 mm. The finite element failure load was 0.6% lower than that observed
in the test.
