- According to their , buildings are mainly of wood structure, masonry structure, reinforced concrete structure, steel structure and mixed structure.
- In general, the damping ratio of steel structures is than that of the reinforced concrete structure. That is, the seismic action of the steel structure is than that of the reinforced concrete structure under the same structure period, mass and other parameters. ( ) A: smaller smaller B: smaller larger C: larger smaller D: larger larger
- Translate the following terminology (术语) into Chinese. civil engineering: structure: steel structure: concrete structure: frame structure: arch structure: cable-suspended structure: shear wall structure: high-rise structure: civil building:
- Under the same site category and intensity conditions, the seismic damage of steel structure building is greater than that of reinforced concrete structure building.
- 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.

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.
