Generally, seismic hazards may be more severe cause by reverse fault than normal fault.

Which is not the principle of seismic design of reinforced concrete structure ( ). A: Strong-column-weak-beam B: Strong-shear-weak-bending C: Strong-joint-weak-member D: Strong-slab-weak-beam

Generally, seismic hazards may be more severe cause by reverse fault than normal fault. A: 正确 B: 错误

Seismic waves include P wave, S wave, Rayleigh wave and Love wave, of which the fastest is P wave.

Under the same site category and intensity conditions, the seismic damage of steel structure building is greater than that of reinforced concrete structure building.

The Seismic Fortification Classification of Buildings categorizes buildings into four groups according to their importance and function of these buildings in earthquake events, among which, the elementary school buildings belong to ( ) Class . A: A B: B C: C D: D

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

Seismic fortification classification criteria standard divides the building into four categories according to the importance of the buildings. Among them, a large number of buildings belonging to ( ), such as general industrial and civil buildings, residential, hotels, etc. A: A Class B: B Class C: C Class D: D Class

For the seismic design of multi-storey masonry building, which statement is not true? ( ) A: the maximum spacing of transverse walls is required to ensure sufficient lateral stiffness of the building. B: Priority should be given to the scheme of transverse wall bearing or longitudinal and transverse wall bearing together C: The width of walls between windows on the same axis should be uniform D: The longitudinal and transverse walls should be aligned along the plane
