Development of Headed Deformed Bars in Tension UpCodes

318 08 defining the development of headed and mechanically anchored deformed bars in tension Section 12 6 Additionally the International Building Code IBC 174 references ACI 318 Terminator effectively reduces the length of reinforcing bar required thus minimizing congestion For example to develop the specified yield strength in a 8 25 mm rebar Terminator A headed deformed bar performs the same as a stan dard hook and is an equal acceptable substitute When calculating the development length for a hooked bar and headed deformed bar using the ACI building code with out reduction factors a headed deformed bar has a 20 reduction in development length when compared to a standard hooked bar

Headed deformed bars gain the strength of the bars though a combination of bearing by the head and bond by the bar deformations With suitable detailing these headed deformed bars can be developed with a shorter length than the straight hooked bars therefore occupying less space 11 10 2013 nbsp 0183 32 A deformed bar anchor is more like a headed stud with deformations on the shaft Typically they thread the end of a reinforcing bar and screw on a quot hockey puck quot The development length is much shorter than a typical rebar and because of the deformations on the shaft it is shorted than a nelson stud They are very useful when you are trying to develop beam

Headed stud vs deformed bar as an anchor Structural

Headed Bars are a simple and effective alternative to hooks and long development length A compact disc is mounted onto the reinforcement bar end The assembly of the rebar and the anchor provides a anchorage superior to Headed deformed bars gain the strength of the bars though a combination of bearing by the head and bond by the bar deformations With suitable detailing these headed deformed bars can be developed with a shorter length than the straight hooked bars therefore occupying less space These headed deformed bars have the capacity to be used in exterior beam column
