Rebar Embedment Length This program calculates embedment and splice lengths for deformed steel rebar in concrete Since typical embedment lengths are readily available in tables this program is primarily for developing tables of embedment lengths when unusual conditions effect the lengths Two major categories of embedment calculation are available Since the required embedment to satisfy anchorage length provisions of the building code typically 40 to 60 bar diameters often greatly exceeds typical anchoring embedment generally limited to 20 bar diameters special precautions may be necessary to ensure that the holes are drilled straight the drilling process does not spall or otherwise damage the existing concrete or Traditionally HILTI tables indicated the required embedment lengths to develop either the yield strength or the tensile strength of the rebar These published embedment embedment length A reinforcing bar must be embed ded or anchored a sufficient distance or length in con crete so the bar will be capable of developing its design strength The basic premise is the anchorage length or embedment length must be equal to or greater than the required tension development length of the bar Regarding Item i provisions in other parts My assumption 2 is that the required embedment depth of a rebar dowel depends on the bond strength of the epoxy mortar and the load that the rebar is required to carry Conservatively consider that M10 rebar is required to have
