Which one of the following statements is correct?
a) Shear cracks start due to high diagonal tension in case of beams with their webs and high prestressing force.
b) Shear design for a prestresed concrete beam is based on elastic theory (Ans)
c) In the zone where bending moment is dominant and shear is insignificant, cracks occur at 20degree to 30 degree.
d) After diagonal cracking, the mechanics of shear transfer in a prestressed concrete member is very much different from that in reinforced concrete members.
