抗震设防等级的确定(国外英文资料) The determination of the level of earthquake resistance (1) the structure of the high-rise building aseismic measures is set according to the seismic grade, the determination of aseismic levels associated with the category of buildings, buildings of different categories when considering seismic grade taking seismic intensity related to the building site categories, namely considering seismic grade access intensity and aseismatic calculation of fortification intensity is not necessarily the same. (2) the construction structure shall be divided into four categories: a, b, c, and ding, according to the importance of its use function. Construction of seismic fortification category to see national standards for the building seismic fortification classification standard GB 50223 rules, also visible building aseismic design manual (1994 edition) high-rise buildings no kind of seismic fortification. Seismic fortification category of high-rise building structure, its aseismatic measures should sign the following requirements: a, b building: 1) when the region seismic fortification intensity is 6 ~ 8 degrees, should accord with the requirement of the region seismic fortification intensity increase once; When the strength of the area is 9 degrees, it should meet the higher requirements than the 9c. When Ⅰ for construction sites, should be in accordance with the requirements of seismic fortification intensity of the region still adopt seismic construction measures; C/c construction: the requirement of the earthquake resistance in this area should be met. When construction sites for class I, in addition to 6 degrees, should be allowed in accordance with the requirements of the region seismic fortification intensity decrease once the seismic tectonic measures. According to the type and site adjusted used to determine the seismic intensity grade, according to the adjusted level of seismic intensity. 3) seismic design, the more tall buildings of reinforced concre
