Maximum tensile strength, failure load
and failure mode were derived and the values compared in each group.
The findings indicated that the near-surface and large sized delamination affect the compressive failure load
and critical buckling load of the structure.
The peak load obtained from both the test was determined as the failure load
and fracture toughness value was calculated using the empirical relations.
Plate fixation was correlated with significantly higher mean values for cycles to failure and peak failure load
and with a significantly lower mean gap width.
Table 5 shows the tensioning force applied to each specimen to reach the initial precamber (the maximum force at failure in the bar) and the failure load
The proposed method predicted the initial subcritical failure load
of 5005 N, similar to the experimental result of 5000 N, with an error less than 0.1%, and the error of bearing failure load
obtained from numerical result of 5561 N and experimental data of 5545 N was only 0.3%.
For comparison with the stipulations of Eurocode-4 , Table 4 arranges the yield load at the bottom flange of the steel girder, the ultimate load, the failure load
, the relative slip at 90% of the failure load
, and the characteristic relative slip measured in the tests.
The failure load
and method of tendon failure were recorded for each specimen.
Modular rail systems were evaluated for repeatability, endurance, rough handling, drop testing, and static failure load
. Where possible, handguards manufactured in different modular rail systems, but otherwise identical, were used as a basis for a comparative analysis.
Note that 30 kN is about 80% of the failure load
of the single-lap double-bolt composite joint.
