The app provides standard rebar specifications including sizes diameters areas and weights along with 90 135 and 180 degree. 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. Reinforcing steel splices standard hooks strength design working stress splices and development length minimum development lengths are necessary to adequately transfer stresses between reinforcement and the grout or mor tar in which it is embedded.

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. Splicing of reinforcement serves a similar purpose. 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. This quick reference app includes information on astm standard reinforcing steel bars rebar standard hook details standard stirrup tie hook details and astm reinforcing bar marking requirements and is handy for both desk and field reference.

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. Howe ve r to maximize the benefits of standard i z a t i o n it is essential that up to date materials standards be re f e r enced in the contract documents.
