RCC Structures Design An R.C.C beam of 25 cm width has a clear span of 5 metres and carries a U.D.L. of 2000 kg/m inclusive of its self weight. If the lever arm of the section is 45 cm., the beam is Safe in shear Is safe with stirrups Needs revision of the section Is safe with stirrups and inclined members Safe in shear Is safe with stirrups Needs revision of the section Is safe with stirrups and inclined members ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design In a doubly-reinforced beam if ‘c’ and ‘t’ are stresses in concrete and tension reinforcement, ‘d’ is the effective depth and ‘n’ is depth of critical neutral axis, the following relationship holds good (m + c)/t = n/(d + n) mc/t = n/(d - n) (t + c)/n = (d + n)/n mc/t = (d - n)/t (m + c)/t = n/(d + n) mc/t = n/(d - n) (t + c)/n = (d + n)/n mc/t = (d - n)/t ANSWER DOWNLOAD EXAMIANS APP
