The equivalent embedment length for allowable stress design ( le = 11.25 db) is based on an allowable stress … 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 transmitted between the concrete (where the load is applied) and the rebar. For this to … See more As previously described, it's generally very desirable to "fully develop" bars, which means providing enough development length that the rebar can reach its full yield strength before ripping out the concrete. This is also reflected … See more When calculating the rebar required in footings, we look at a critical section for bending moment, generated by the action of load being spread … See more If we don't want to deal with rebar development length, there's one simple solution: skip the rebar!
