- Abstract
- This study is to examine bond strength of beam reinforced with GFRP rebar under 4 point
fatigue bending test by adopting BRITISH STANDARD. The variables were made to have
bonding length of 5times(5db), and 15times(15db) of the nominal diameter of GFRP rebar
and were done to analyze the relationship between the bonding strength and the slip. In the
result of the test, pull out failure was dominant in the 5db specimen, patterns of the
pull out failure and concrete shear failure appeared in the 15db specimen showed only
concrete shear failure at the end of bonding length. Therefore, The strain development
consist of three different stage : A rapid increases form 0 to about 10% of total fatigue life.
A uniform increases form 10% to about 70%~90%. Then a rapid increases until failure, if
failure takes place. It seems that stress level has not influence on the secant modules of
elasticity. And also according to the outcome the existing strengthening method came out to
be the most superiority in S N graphs.
