engineering recuitment JSSC JE Mock Test 2023 Reinforced Concrete Structures Bond, Anchorage and Development Length
Generally in R.C.C sections the development length of bars is given by which of the following expressions as per IS standards?
(Here: σs = Stress in the bar at the section considered at design load, ϕ = Nominal diameter of the bar,
τbd = Design bond stress, Ld = Development length of bars)
1
\(\rm L_d=\frac{\phi\sigma_s}{2\tau_{bd}}\)
2
\(\rm L_d=\frac{\phi\sigma_s}{4\tau_{bd}}\)
3
\(\rm L_d=\frac{\tau_{bd}\sigma_s}{5\phi}\)
4
\(\rm L_d=\frac{\tau_{bd}\sigma_s}{7\phi}\)
