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 Needs revision of the section Is safe with stirrups Is safe with stirrups and inclined members Safe in shear Needs revision of the section Is safe with stirrups Is safe with stirrups and inclined members ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If the length of a combined footing for two columns l meters apart is L and the projection on the left side of the exterior column is x, then the projection y on the right side of the exterior column, in order to have a uniformly distributed load, is (where x̅ is the distance of centre of gravity of column loads). y = L/2 + (l - x̅) y = L - (l - x̅) y = L/2 - (l + x̅) y = L/2 - (l - x̅) y = L/2 + (l - x̅) y = L - (l - x̅) y = L/2 - (l + x̅) y = L/2 - (l - x̅) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If Sb, is the average bond stress on a bar of diameter ‘d’ subjected to maximum stress ‘t’, the length of the embedment ‘l’ is given by l = dt/4Sb l = dt/2Sb l = dt/Sb l = dt/3Sb l = dt/4Sb l = dt/2Sb l = dt/Sb l = dt/3Sb ANSWER DOWNLOAD EXAMIANS APP
