Civil Engineering :: Concrete Technology and Design of Concrete Structures
- If the storey height is equal to length of RCC wall, the percentage increase in strength is
- Modulus of elasticity of steel as per IS : 456-1978 shall be taken as
- The main reason for providing number of reinforcing bars at a support in a simply supported beam is to resist in that zone
- The strength of concrete after one year as compared to 28 days strength is about
- For a reinforced concrete section, the shape of shear stress diagram is
- In prestressed concrete
- Due to shrinkage stresses, a simply supported beam having reinforcement only at bottom tends to
- The centroid of compressive force, from the extreme compression fiber, in limit state design lies at a distance of (where xu is the depth of neutral axis at the limit state of collapse)
