CRANKED BAR / BENT UP BAR:
A bent-up bar called as crank bar is provided to make RCC slab safe from compressive stresses. When bent up bars are provided, the strength and deformation capacity of slabs with bent up bars compared to slabs without bent up bars is sufficiently increased.
Generally in the fixed R.C.C ended Slabs, means column at the ends of the supports. Those slabs face Two types of moments develop which are called.
1. The positive moment which called (Sagging) develop at mid of the span.
2. The negative moment which called (Hogging) develop at the supports.
Crank bars or bent up bars are provided in a slab due to the following reasons :
1. To resist positive bending moment or sagging BM at the mid span. This is done by the bottom reinforcement provided in a slab.
2. To resist negative bending moment or hogging BM at the support of the slab. This is done by the top reinforcement provided in a slab.
3. To resist the shear force which is greater at the supports.
4. To reduce the risk of a brittle failure of slab- column connection.
5. To reduce the amount of steel used.
6. For the economization of materials.
Bars are bent near the supports at an angle of 45° and having length 0.42 D (D is the c/c distance from top & bottom reinforcement). Crank distance is L/5 from intermediate support and L/7 from end support.

Crank ൻ്റെ length എങ്ങനെ 0.4D ആകാൻ കഴിയും?.
മുകളിലും താഴെയും ഉള്ള ബാറുകൾ തമ്മിലുള്ള വിത്യാസം D ആണെങ്കിൽ അതിൻ്റെ hypotenuse ആയി വരുന്ന ഭാഗത്തിന് എങ്ങനെ D യിലും കുറഞ്ഞ അളവ് (0.4D) വരാൻ പറ്റും?

[@sreenathpv1654]

1.414 D its correct
