WebDevelopment of bundled bars Individual bar development length within a bundle, in tension or compression, shall be that for the individual bar, increased 20 percent for three-bar bundle, and 33 percent for four-bar … Webnumber of bar ;\ = Modification factors for development bars (ACI 318-14 table 25.4.2.2.). When the requirement of development length of straight anchorag e bar do exceed the element dimension, the hooked bar can be utilized as an alternative. The hooked bar reach their anchorage by combination of bond and direct bearing of the hook on concrete.
