can somebody explain to me what constitutes structural reinforcing steel for the perimeter surface for 680.26, the alternate means spells out exactly what is required to comply

The structural reinforced steel is the steel within the pool not the steel that may be in the perimeter surface. I am confused by your question.

680.26 (B) (2) gives you two options, structural reinforcing steel or the alternate means for the perimeter surface, if i had a rebar pool that was 20ft by 15ft would 4 pieces of rebar uniformly spaced, attached to the pool structure, extending 3ft horizontally comply

I thought the perimeter surface had to follow the contour of the pool. Thus 3' horiz. out from the pool and around the entire pool (perimeter)

the alternate means shall follow the contour of the pool, i can't find that requirement for structural reinforcing steel, maybe i am missing something

the alternate method is a #8 solid wire 18" to 24 " from the water that follows the contour of the pool all the way around.

that is correct, but what would constitute structural reinforcing steel for the perimeter surface

I would think it would pertain to any steel that is installed in a concrete perimeter but generally there is no steel in these walking areas. Structural steel pertains, IMO, to the pool steel.

do you think my example in post #3 complies as structural steel for the perimeter surface
 
mpd, good question. I don't think the steel in post #3 would suffice but that is just an opinion. One would have to define "structural steel" for the correct answer, I guess, but some type of bar or mesh would have to at least follow the entire contour of the pool before I would want to accept it.

That is the pool wall steel rolled up and over into the deck. It is an extra and not required. It extends out 3' from the water and sometimes all the way back to the house when pools are attached to the house as they are here in Florida. Many pool builders do this to prevent cracked decks which are also common in Florida just like mine is cracked in three places.

Structural reinforcing steel is also the 4" square wire mesh installed in the deck concrete to try to stop the cracks. It does not work.

but does the NEC 2008 define what is structural reinforcing steel for the perimeter surface, contractors around do the same thing usually wire mesh in the concrete bonded to the pool structure, but i am not sure the NEC requires this, thanks for the replies
 
The Code does not require the wire mesh, it requires the perimeter surfaces to be bonded and I believe most inspectors accept the wire mesh as "structural steel".
