Question Sir ,
can you briefly explain how are the anti crack rebar provided in a pile cap. as we know that pile cap will have top and bottom bars along both directions and also face bars provided parallel to side faces, then can you indicate with a sketch or demonstrate where anti crack bars are provided with a detail and also clarify whether these bars are lapped with face bars or main bars? also illustrate what is the use of providing anti crack bars?
Answer Dear Arsalan
Anti crack reinforcement is a minimum reinforcement in a section which is not needed to consider separetely if you provided a calculated amount. Then I dont think that if you have a minimum in each way you dont need to provide it .
