Answer / yogesh jadhav

as per IS 456 2000
development length formula is Ld=0.87fyd(dia)/4tbd
tbd for various concrete is M20=1.2 m25=1.4 m30=0.5 m35=1.7
m40 and above=1.9
for deform bars 60%increase the value of tbd for compression it is increse by 25%
for example m25 grade concrete and fy 415
ld=0.87*415*D/4*1.4*1.6=40.29D
for m25 and fy=500 ld=48.54D approx 50D
anchorage length=Ld+2D
straight anchorage length=SAL=AL+8D
