- Since concrete is a kind of elastoplastic materials, when calculating the torsional bearing capacity of plain concrete member, elastic analysis method should be adopted.
- Since concrete is a kind of elastoplastic materials, when calculating the torsional bearing capacity of plain concrete member, elastic analysis method should be adopted. A: 正确 B: 错误
- The main reason why spiral stirrups can improve the bearing capacity of the normal section of axial compressed columns is that ( ). A: the strength of spiral stirrups is high B: spiral stirrups can effectively restrain the longitudinal reinforcements and improve the compressive strength of longitudinal reinforcements C: spiral stirrups can effectively restrain the core concrete and improve its compressive strength D: spiral stirrups have strong deformation capacity
- Which of the following is not the reason why concrete needs reinforcement? A: Reinforcement has good tensile resistance, while concrete has good compressive resistance. B: Reinforcement has good compressive resistance as concrete. C: Engineers prefer ductile failure to brittle failure of the members. D: Reinforcement and concrete can work together to increase the bearing capacity of the members.
- The shear bearing capacity of small-eccentrically tensioned member will increase with axial force increasing
