Maximum shear force in midspan D. Minimum shear force at support 3The following statement about structural earthquake resistance is correct. A. Structural earthquake is the main research area of building seismic resistance. B. "Medium earthquake repairable" means that it can continue to be used without repair when it is affected by earthquakes equivalent to the seismic fortification intensity of the region. C. Using cast-in-place concrete staircase structure is an effective measure to improve the seismic performance of masonry structure of multi-storey buildings. D. According to the importance of building function, a large number of buildings belong to category A and B seismic fortification in practice. 4After a high-rise building was put into use, it was found that the wall of fire water storage pool was slightly cracked and the leakage could not meet the normal use, which affected the structure of the building. A. Safety B. Applicability C. Practicality D. Durability 5The following is a mistake in the construction requirements for reinforcement of reinforced concrete beams. A. The failure of normal section of reinforced concrete beams is that steel bars yield first and concrete is crushed later. B. The failure of over-reinforced and less-reinforced beams is usually brittle without any warning. C. Proper allocation of stirrups and distribution of reinforcing bars are effective measures to prevent the failure of oblique sections. D. The web reinforcement in the beam has some influence on the mechanical performance of the oblique section. 6The height of masonry wall of a building is 2.2 meters and the thickness of wall is 320 mm.
