Four sided concrete roof
Four sided concrete roof
(OP)
Im an entry level engineer and have never designed a four sided roof (i think thats the term in english). I was wandering i you knew where to find information in regards on how to specify the reinforcement.

Are you sure that this is meant to be done in concrete? It is usual to do this type of roof in timber trusses.

Yes. It is done in Puerto Rico where I live.

Watch out for the bowstring effect at the crank at the top. The bottom reinforcement should continue up to lap with the top reinforcement frm either side (i.e. a kind of a splice).
Otherwise if you just had a bent piece of bar it would want to straighten and would therefore break out of the cover concrete (like a bowstring).
