    2.what is the two legged  ad four legged stirrups
    3.what is the  purpose of cranking

Answer
Dear Ragavi

1 and 2- Shear reinforcement is used for stirrups which are installed in vertical or oblique position in RC giders to prevent the tensile cracks due to shear being developped in the member. Stirrups can have some shape like 1 leg, 2 legs, hoops and the can be combined together to provide the desired shear resistance in the section.

3 and 4 - I dont know them.
