According to their , buildings are mainly of wood structure, masonry structure, reinforced concrete structure, steel structure and mixed structure.
materials of the load-carrying frame
举一反三
- 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
