Midspan deflection (mm)

Figure 7.7 Load-midspan deflection of composite girder G1 obtained experimentally
and numerically.

Figure 7.7 . It can be shown that generally good agreement was achieved
between experimental and numerical relationships. The ultimate failure load
observed in the test [ 7.29 ] was 1743.7 kN at a deflection of 95.6 mm, while
the ultimate failure load predicted from the finite element analysis was
1765.5 kN at a deflection of 97.7 mm. The finite element failure load
was 1.3% higher than that observed in the test.
