RCC Structures Design With usual notations the depth of the neutral axis of a balanced section, is given by t/mc = (d + n)/n mc/t = n/(d - n) t/mc = (d - n)/n mc/t = (d - n)/n t/mc = (d + n)/n mc/t = n/(d - n) t/mc = (d - n)/n mc/t = (d - n)/n ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design A pre-stressed concrete member is preferred because Removal of cracks in the members due to shrinkage All listed here Large size of long beams carrying large shear force need not be adopted Its dimensions are not decided from the diagonal tensile stress Removal of cracks in the members due to shrinkage All listed here Large size of long beams carrying large shear force need not be adopted Its dimensions are not decided from the diagonal tensile stress ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If A is the area of the foundation of a retaining wall carrying a load W and retaining earth of weight 'w' per unit volume, the minimum depth (h) of the foundation from the free surface of the earth, is h = √(W/Aw) [(1 - sin φ)/(1 + sin φ)]² h = (W/Aw) [(1 + sin φ)/(1 + sin φ)] h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]² h = (W/Aw) [(1 - sin φ)/(1 + sin φ)] h = √(W/Aw) [(1 - sin φ)/(1 + sin φ)]² h = (W/Aw) [(1 + sin φ)/(1 + sin φ)] h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]² h = (W/Aw) [(1 - sin φ)/(1 + sin φ)] ANSWER DOWNLOAD EXAMIANS APP
