据历史研究成果,上海市一直被认为是地震少发区,其基本烈度为6度,按以往的规定,6度区内的房屋建筑是无需设防的。1984年,建设部从尽可能减少灾害损失着眼,以(84)城抗267号文规定:“基本烈度6度地区的省会和市区人口在百万以上的城市,位于市区的9类新建工程按7度设防。”根据这一文件精神,上海市规定:“自1987年起,市区22类与市郊9类主要新建筑需按烈度7度区设防。”与此同时,在市科委与市建委牵头下,上海市抗震办公室于1986～1988年组织了“上海市抗震防灾基础技术研究”,其中包括:上海地区防震危险性分析及烈度复核、上海地区地震小区划、震害预测等专
According to historical research results, Shanghai has been considered to be an earthquake-prone area with a basic intensity of 6 degrees. According to past regulations, housing buildings in the 6-degree area do not need to be fortified. In 1984, the Ministry of Construction focused its attention on minimizing disaster losses. It was stated in (84) Cheng-Chan 267 that “The provincial capital with a basic intensity of 6 degrees and cities with a population of more than one million in urban areas are located in 9 new types of urban areas. The project is based on a 7-degree fortification.” According to the spirit of this document, Shanghai stipulates: “Since 1987, 9 major new buildings in urban areas and 9 suburbs in urban areas are required to be fortified at a 7-degree intensity.” At the same time, Under the leadership of the Committee and the Municipal Construction Commission, the Shanghai Office for Earthquake Resistance organized the “Research on Basic Technologies of Earthquake Disaster Prevention in Shanghai” from 1986 to 1988, which included: analysis of earthquake risk prevention in Shanghai area, review of intensity, regionalization of earthquakes in Shanghai area, earthquake damage Forecast and other special
