举一反三
- The bearing capacity of axially loaded compression member in the steel structure is generally determined by (). A: stiffness B: strength C: stability D: section
- When foundation deformation is allowed and the ground is stable, the capacity to withstand the load per unit area is called the bearing capacity of ground.（ ）
- 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
- 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.
- ( ) is an important means of strengthening metal materials. A: elastic deformation B: plastic deformation C: stretching D: fibrous structure
