Reinforced concrete beams work with cracks under normal load.
举一反三
- Reinforced concrete beams work with cracks under normal load. A: 正确 B: 错误
- In terms of the flexural stiffness of reinforced concrete beams, which of the following statements is wrong. A: The bending stiffness of reinforced concrete beam varies in the process of loading B: The short-term bending stiffness of reinforced concrete beams is derived from the curvature relation of cross-section C: The short-term average bending stiffness is adopted in the deflection checking calculation D: The bending stiffness under long-term load is smaller than that under short-term load
- Reinforced concrete beam is under normal service loads, and A: it usually works with cracks B: once the cracks appear, the crack is passing through to the total section C: once the cracks appear, the bonding force between the concrete and the reinforcement along the full length is lost D: it usually does not develop cracks
