RCC Structures Design In a singly reinforced beam Plane sections transverse to the centre line of the beam before bending remain plane after bending Compression is borne entirely by concrete Elastic moduli for concrete and steel have different values within the limits of deformation of the beam Steel possesses initial stresses when embedded in concrete Plane sections transverse to the centre line of the beam before bending remain plane after bending Compression is borne entirely by concrete Elastic moduli for concrete and steel have different values within the limits of deformation of the beam Steel possesses initial stresses when embedded in concrete ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design Long and short spans of a two way slab are ly and lx and load on the slab acting on strips parallel to lx and ly be wx and wy respectively. According to Rankine Grashoff theory None of these (wx/wy) = (ly/lx)⁴ (wx/wy) = (ly/lx) (wx/wy) = (ly/lx)² None of these (wx/wy) = (ly/lx)⁴ (wx/wy) = (ly/lx) (wx/wy) = (ly/lx)² ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If ‘p’ is the net upward pressure on a square footing of side ‘b’ for a square column of side ‘a’, the maximum bending moment is given by M = pb (b + a)/8 M = pb (b - a)²/8 M = pb (b + a)/8 M = pb (b - a)²/4 M = pb (c - a)/4 M = pb (b + a)/8 M = pb (b - a)²/8 M = pb (b + a)/8 M = pb (b - a)²/4 M = pb (c - a)/4 ANSWER DOWNLOAD EXAMIANS APP
