Dh of bars with standard hooks are based on 22 tests reported by marques and jirsa 1975 which used neither highstrength steel nhighor strength concrete. Astm s steel standards are instrumental in classifying evaluating and specifying the material chemical mechanical and metallurgical properties of the different types of steels which are primarily used in the production of mechanical components industrial parts and construction elements as well as other accessories related to them.

Many drawings refer to standard hooks and show hooked bars in specific areas for top and bottom reinforcing. To meet the needs of our customers we display some rebar sizes charts so that it is easy to choose the most suitable rebar you wanted. Recently the use of. 90 degree hooks those that have a 12 bar diameter extension on the hook leg pin to end 180 degree hooks and stirrup and tie hooks those that have a 6 to 12 bar diameter.

Reinforcing steel for these tests had yield strengths 64 and 68 ksi and of the compressive strengths of the concrete were between 3 750 and 5 100 psi. Reported by the masonry standards joint committee 2002.
