In conventional reinforced concrete, the high tensile strength of steel is combine with concrete's great ________________ to form a structural material that is strong in both ________ and ________.
举一反三
- Reinforced concrete has steel bars that are placed in the concrete to carry tensile forces.
- Concrete is basically a compressive material and has good tensile strength.
- The truncated position of the longitudinal steel bar in the reinforced concrete beam is at the point where the steel bar is fully utilized.
- The reinforced concrete construction with aluminum surface enhanced structural design and reduced its costs.
- Under a certain long-term load, concrete would creep. In the reinforced concrete axial compressive members: A: Creep increases the compressive stress of concrete. B: The compressive stress of concrete and steel bar keeps unchanged. C: Creep decreases the compressive stress of concrete and increases the compressive stress of steel bar. D: Creep increases the compressive stress of concrete and decreases the compressive stress of steel bar.
