๐Some Note Points of RCC:-
๐กIS 456:2000 is not applicable to grade above M-60
(Amendment no. 4 May 2013)
๐กIS 456:2000 recommends minimum grade as M20 for RCC.
๐กPartial Safety Factor for Concrete (i.e 1.5) is more than that of Steel (1.15) because the control on Quality of Concrete is not good as that of Steel.
๐กDeflection can be reduced by providing more Tensile Steel than required for Flexure,the service stress in steel is reduced & Hence the Deflection.
๐กShrinkage Deflection in case of Rectangular Beams & Slabs can be eliminated by putting Compression Steel equal to Tension Steel.
๐กNegative moment in Reinforced concrete beams at the location of support is generally much higher than positive span moment.This is Primarily due to Curvature at the Support being very high....
๐กIf beam is Over-Reinforced,
the beam will not have Ductile Failure.
