A: smaller smaller
B: smaller larger
C: larger smaller
D: larger larger
A: smaller smaller
B: smaller larger
C: larger smaller
D: larger larger
举一反三
- Under the same site category and intensity conditions, the seismic damage of steel structure building is greater than that of reinforced concrete structure building.
- According to their , buildings are mainly of wood structure, masonry structure, reinforced concrete structure, steel structure and mixed structure.
- The size of this city is_______ that city by over three times. A: smaller than the size of B: smaller than the height of C: larger than the weight of D: larger than that of
