Design of Reinforced Concrete Structures 2Take a Quiz on Design of Reinforced Concrete Structures 21. Which of the following stress-strain curves are usually used to idealize behavior of concrete? Parabolic Curve Bilinear Curve Both2. In a balanced reinforced beam, the ratio of steel to concrete is in such a way that, strain in both the materials reach maximum simultaneously. True False3. Limit state method of design is a Stress controlled approach Strain controlled approach Both4. Which of the following method of designing beam provides sufficient alarming deflection before failure? Balanced reinforced beam Over-reinforced beam Under-reinforced beam none of the above5. Failure mode of an over reinforced beam is ____________ in nature. Ductile Brittle Both6. At ultimate moment of resistance, factored bending moment = resisting moment factored bending moment < resisting moment factored bending moment > resisting moment7. Usually, maximum strain in concrete is assumed to be, 0.35 % 0.0035 % 0.33% 0.003%8. In a simply supported beam with a point load at mid span, Bottom fiber is under tension Bottom fiber is under compression Bottom fiber is under torsion none of above9. Maximum depth of neutral axis in design of a RC beam is restricted in-order to avoid brittle failure Maximum strain in steel is achieved before failure to keep the section under-reinforced All of the above10. Limiting tensile reinforcement for a section is obtained by equating Compression to Tension. True FalseBe sure to click Submit Quiz to see your results! Name Email Time is Up!
