Determination of effective length of cantilever beam ...

effective length = length of clear span + half of effective depth of beam. effective depth = depth _ effective cover. efective cover = Clear cover + half dia of main reinforcement. effective cover = 25 mm + Dia/2. effective cover = 25 mm + 12/6 mm. Effective cover = 25+6 =31 mm putting this value. effective depth = 300 mm _31 = 271 mm
