What does the school aseismic fortify standard have to ask?After the Wenchuan earthquake in 2008, the newly revised Law of the People’s Republic of China on Earthquake Protection and Disaster Reduction clearly stipulates that: For the construction of schools, hospitals and other densely populated places, the design and construction should be carried out in accordance with the requirements of earthquake protection higher than that of local buildings and buildings, and effective measures should be taken to enhance earthquake protection capacity;Where the seismic fortification measures have not been taken or the seismic fortification measures have not met the requirements for seismic fortification, the seismic performance shall be appraised according to relevant regulations and necessary measures for seismic reinforcement shall be taken.In 2008, the ministry of Housing and urban and rural development and other departments revised “construction engineering seismic fortification classification standard” (GB50223-2008) provision, education building, kindergarten, primary school, middle school teaching rooms and student dormitories and canadolescents, seismic fortification category should not be lower than the key fortification category.Seismic fortification standard requirements for key fortification buildings: seismic fortification measures should be strengthened according to the requirements of earthquake fortification intensity one degree higher than the local area;But when the seismic fortification intensity is 9 degrees, seismic measures should be taken according to higher requirements than 9 degrees.Seismic measures for foundation shall conform to relevant regulations.At the same time, the seismic effect should be determined according to the intensity of seismic fortification in this area.Seismic reinforcement design provisions of the current standard “building seismic fortification classification standard” GB50223 is divided into four categories, its seismic checking and seismic structural measures appraisal should meet the following requirements: class A building, should be specially studied to determine.The verification and reinforcement of the seismic measures shall be carried out according to the requirements of class B buildings, and the seismic checking calculation shall be carried out according to the requirements of the seismic fortification intensity higher than the local area;Class B buildings, 6 degrees to 8 degrees, the seismic inspection and reinforcement measures should be implemented in accordance with the requirements of earthquake fortification intensity increased one degree than this area, 9 degrees should be appropriately raised requirements;The aseismatic checking calculation shall be carried out according to the requirements of the aseismatic fortification intensity of the region;For class C buildings, seismic verification, reinforcement and seismic checking shall be carried out according to the local seismic fortification intensity;For class D buildings, when 7 ~ 9 degrees, the verification and reinforcement of seismic measures should be allowed to be implemented according to the requirement of reducing the fortification intensity by one degree.The aseismic checking calculation shall be allowed to be carried out in accordance with the requirements of reducing the fortification intensity appropriately compared with the local area.6 degrees shall not be allowed for seismic evaluation.
