Answer Posted / madhukeshwara`

d=16 mm for compression steel
stress in bar =0.87 times of 415 N/mm2 = 361.05N/mm2
design bond stress for M20 CONCRETE = 1.2 N/mm2
then,
Ld = 16 x 361.05 /4 x 1.6X 1.2 = 752.02 mm

d=16 mm for tension steel
stress in bar =0.87 times of 415 N/mm2 = 361.05N/mm2
design bond stress for M20 CONCRETE = 1.2 N/mm2
then,
Ld = 16 x 361.05 /4 x 1.25X 1.2 = 962.8 mm
