Answer to Question #221581 in Civil and Environmental Engineering for Samistha Pattnaik

Question

calculate development length required to be provided for m25 concrete and fe415 steel of diameter phi for bar in tension zone and in compression zone

Answer 1

Development length under Tension:

stress in bar = 415 Mpa

Bond stress M25 = 1.44

Diameter = phi

l.d = $(415 * \Phi) / (4 * 1.44 * 1.6)$

l.d = $45.03\Phi$

Development Length under compression

l.d = $(415 * \Phi) / (4 * 1.44 * 1.25)$

l.d = 57.639$\Phi$
