Shenzhen housing safety testing center specializing in detecting primary and secondary schools, kindergartens, Shenzhen seismic safety inspection reports, school reinforcement detection and identification, detection and identification of school safety reporting structure. Tel: 15220141392 China's "earthquake-proof construction engineering classification criteria" (GB50223-2008) stipulates that construction projects should be divided into the following four categories of earthquake-proof; (1) special fortification categories: refers to the use of special facilities, involving national public In particular the consequences of major disasters that may occur when the safety of major construction projects and serious secondary disasters such as earthquakes, the need for special fortified building. Referred to as the CPI. (2) focus on fortification categories: use the function refers to an earthquake can not be interrupted or need to recover as quickly as possible lifeline related buildings, as well as the consequences may lead to a major disaster such as an earthquake large number of casualties, the need to improve the standard of building fortifications. Referred to as B. (3) Standard fortification class: refers to a large number of special fortification in addition to classes focused on fortification class, outside class according to standards appropriate fortification fortification building. Referred to as Class C. (4) moderate fortification class: refers to the use of scarce personnel and earthquake damage will not produce secondary disasters, under certain conditions, allow a modest reduction in the required building. Referred to as D class. "Construction Engineering classification of seismic standards": education buildings, teaching buildings kindergarten, primary school, secondary school and student dormitory and cafeteria, seismic design category shall not be less than the focus of fortification category.
