STRUCTURAL ANALYSIS QUIZ 1 Welcome to QUIZ FOR ASPIRANTS 1. The joint action of steel and concrete, in a reinforced concrete section, depends upon the bond between concrete and steel bars absence of corrosion of steel bars embedded in the concrete practically equal thermal expansion of both concrete and steel all of the above2. A twisted bar has about ............ more yield stress than ordinary mild steel bar. 10% 20% 35% 50%3. The application of elastic theory to the beams is based on the assumption that at any cross-section, plane sections before bending remain plane after bending all tensile stresses are taken up by reinforcement alone and none by the concrete steel reinforcement is free from initial stresses when it is embedded in concrete all of the above4. In a singly reinforced beam, the effective depth is measured from the compression edge to the tensile edge centre of tensile reinforcement neutral axis of the beam none of the above5. In a simply supported reinforced concrete beam, the reinforcement is placed below the neutral axis above the neutral axis at the neutral axis any of these6. The compressive strength of concrete is about 10 to 15% of its tensile strength True False7. In case of a cantilever beam, the tensile zone is above the neutral axis. Agree Disagree8. In reinforced cement concrete structures, the steel reinforcement consists of deformed bars cold twisted bars mild steel and medium tensile steel bars all of these9. Analysis of reinforced concrete can be done by straight line theory elastic theory ultimate theory all of the above10. In singly reinforced beams, steel reinforcement is provided in tensile zone compressive zone both tensile and compressive zones neutral zone Name Time is Up!
