RCC Structures Design Set 4

Compression is borne entirely by concrete ✘ Steel possesses initial stresses when embedded in concrete ✘ Plane sections transverse to the centre line of the beam before bending remain plane after bending ✘ Elastic moduli for concrete and steel have different values within the limits of deformation of the beam ✔

Is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier ✘ Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier ✘ Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum stresses simultaneously ✘ All the above ✔
