举一反三
- The shear bearing capacity of small-eccentrically tensioned member will increase with axial force increasing A: 正确 B: 错误
- When calculating the bearing capacity of members under combined load of shear and torsion, the interaction relation between shear and torsion should be considered for concrete bearing capacity while the reinforcement bearing capacity is just the linear superposition of shear bearing capacity and torsional bearing capacity of reinforcement.
- With the increasing of the foundation width, the bearing capacity of<br/>the soil tends to ( ) A: increase B: not change C: decrease D: uncertain
- With the increasing of the foundation embedment depth, the bearing capacity of the soil tends to ( ) A: increase B: not change C: decrease D: uncertain
- The main difference of the failure characteristics between the large and small eccentrically compressed reinforced concrete members is whether the reinforcement on the far-side from the axial force is in tension or compression at the failure.

In order to ensure the reliability of prestressed concrete axial tension members, in addition to the calculation of bearing capacity and crack control, the calculation of bearing capacity in construction stage and the local pressure of concrete at the end of post-tensioning members should also be carried out.
