WebA development length relates to the quantity of rebar length that is required to be implanted into concrete to generate desired bond force between the two components and to originate desired stress in steel at … When calculating the rebar required in footings, we look at a critical section for bending moment, generated by the action of load being spread uniformly from the column to the entire area of the footing. As you can see on the image below, the available length for development of the rebar is the distance … See more Steel reinforcement (rebar) in concrete footings generally acts in tension to resist bending loads that arise as the footing spreads loads uniformly over the soil underneath. However, those tension loads have to be … See more As previously described, it's generally very desirable to "fully develop" bars, which means providing enough development length that the rebar … See more If we don't want to deal with rebar development length, there's one simple solution: skip the rebar! Indeed, the ACI code specifically allows concrete footings to be designed without any rebar, using the small tensile … See more
