举一反三
- A plain concrete usually has a ___ amount of cement compared to lean concrete. A: higher B: lower C: neither A or B D:
- The specific meaning of the terms "reinforced concrete and prestressed concrete" are ______ .
- Which of the following is the mostly used type of concrete pavement? A: Jointed plain concrete pavement (JPCP) B: Jointed reinforced concrete pavement (JRCP) C: Continuously reinforced concrete pavement (CRCP) D: Prestressed Concrete Pavements (PCP)
- 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.
- Consider a cement wall reinforced with steel bars. Into which category of materials would you place reinforced concrete? A: Metals B: Non Metals C: Composites D: Ceramics
内容
- 0
Reinforced concrete has steel bars that are placed in the concrete to carry tensile forces.
- 1
What is the use of the reinforced concrete?
- 2
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.
- 3
Compared with plane concrete beams, reinforced concrete beams have much higher cracking resistance(抗裂能力).
- 4
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 ________.
