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.

举一反三
- When the normative method determines the formula for calculating bearing capacity of ground, fa is（ ） A: characteristic value of bearing capacity of ground B: modified characteristic value of bearing capacity of ground C: correction coefficient of bearing capacity of ground D: uncertain
- The shear bearing capacity of small-eccentrically tensioned member will increase with axial force increasing
- Since concrete is a kind of elastoplastic materials, when calculating the torsional bearing capacity of plain concrete member, elastic analysis method should be adopted.
- The shear bearing capacity of small-eccentrically tensioned member will increase with axial force increasing A: 正确 B: 错误
- 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.
