举一反三
- Concrete is basically a compressive material and has good tensile strength.
- Which of the following is NOT considered as a property of asphalt concrete? A: Thermal cracking resistance B: Tensile strength C: Compressive strength D: Fatigue crack resistance
- The common failure characteristic for the large and small eccentrically compressed reinforced concrete members is that the concrete in compression zone reaches the concrete ultimate compressive strain at the failure.
- 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.
- 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.
