Freecycle: Broken Fort Track 7005

I am just now studying the effects of GFRP or CFRP strengthening of beams, columns and slabs. As the fort is neither a beam, nor a column, nor slab, and in addition is not made of concrete or steel, and is most probably subject to impulsive or harmonic loadings rather than statics, I will skip my original idea of a bond strength analysis and move straight to my gut response:

"brittle failure ahoy" :-)

(I'm sure you know that though Brucy. Looks like fun. Have you steepened the head angle compared to the original geometry?)

Grp was designed to replace wood on planes harmonics i think not:) anyways what you studying?
