Flexural Response of RC
17 important questions on Flexural Response of RC
How are the strain assumed to vary over depth of a bending member?
Define flexure from the perspective of the internal axial forces
Define curvature in terms of i) Beam deflections ii) sectional strain
- Sectional Strain: Rate of strain change over depth. Deformation under bending
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
In a linear member. The slope of bending moment - curvature response is constant. What is the name for bending moment per unit curvature? The slope is equal to the product of which material and geometrical parameters?
Why is contribution from reinforcement towards the cracking resistance of a concrete member not accounted for in members with low percentages of reinforcement?
Why is the contribution from reinforcement towards the cracking resistance of a RC not accounted for in members with high % of reinforcement?
If the purpose of non-prestressed reinforcement is not to increase cracking load then what is the purpose?
Explain why prestressed concrete is typically precast in a factory rather than cast in place
What is the tensile strength of a typical 13 mm 7-wire prestressing strand?
Why does prestressed concrete need to be constructed using a high strength steel?
Give an example of a common precast pretensioned prestressed concrete member
Give an example of a common cast-in-place post-tensioned prestressed concrete member
How does prestressing increase cracking strength?
What is the physical meaning of EcIcr
For a both-ends continuous slab, what is minimum depth of slab to avoid having to calculate dispacements?
