Building seismic grade standard

Building seismic fortification categories can be divided into special fortified class ( Such as the national public security construction, key fortification, standard of fortification and moderate fortification. Each category has different seismic fortification standards, such as fire disaster relief buildings, public buildings and residential buildings. 1. Fire disaster buildings, cities and industrial and mining enterprises, for example 1 building fire disaster relief should be based on its social influence and role in earthquake relief for seismic fortification classification; The seismic fortification category 2 medical building, should be set according to the following requirements: a. Tertiary hospital responsible for particularly important medical hospital, medical, outpatient service, seismic fortification class as a class; （ Classification reference use fixed number of year for design of building structure and seismic safety grade b. Secondary and tertiary hospital be in hospital, medical, outpatient service, has the surgery or the emergency department in towns and townships, the headquarters of the emergency center at or above the county level, transportation systems, and other important buildings, seismic fortification category b; c。 Industrial and mining enterprises of medical treatment and buildings in the city's medical building sample to determine its seismic fortification 3 fire and its duty room, garage seismic fortification category should be classified as class b; 4 towns, counties and county-level cities in more than 200000 population of fire emergency command center of the main building, seismic fortification category should not be lower than b; 5 centers for disease control and prevention in construction of seismic fortification category, shall meet the following requirements: a. Undertake research, pilot and storage of toxic dangerous infectious viruses task of the centers for disease control and prevention of buildings and their extents, seismic fortification class should be a class; b。 Do not belong to a of counties, county-level cities and above the centers for disease control and prevention of the main building, seismic fortification category b. 2. Public buildings and residential buildings under seismic fortification category applies to sports buildings, shopping malls, theaters, museums, archives, exhibition center, exhibition center, education buildings, hotels, office buildings, scientific experiments and other public buildings and residential buildings such as residential, dormitory, apartment. 1 public buildings, should be used according to the intensity, functions, scale, the social impact caused by the earthquake and the size of the direct economic loss of division of seismic fortification level; 2 building of sports, size class for large stadium, large, medium, and the gym, seismic fortification should b; 3 cultural buildings, large cinema, theatre, auditorium, exhibition hall, etc. , seismic fortification should b; 4 commercial buildings, the crowded large multilayer mall, seismic fortification level should be b; When commercial buildings and other structures built together, should judge situation respectively, as defined by the section and the seismic fortification level; 5 in museums and archives, large museums, deposited at the national level cultural relics museum, archives, super, serie a seismic fortification level for b; Six exhibition buildings, large exhibition center, exhibition center, seismic fortification category b; 7 education buildings, kindergarten, primary and secondary schools teaching occupancy level of students' dormitory and canteen, seismic fortification level shall not be lower than b; 8 scientific experiment building, research, for dangerous and poisonous items, such as virus, seismic fortification class as a class; Number 9 high-rise building, the use of more than 8000 people, the seismic fortification should b; The seismic fortification should not be less than 10 residential building c class. Above the seismic grade standards for construction
