现有建筑物抗震加固和城市抗震防灾规划编制工作正在进行。这是减轻地震灾害的两项极为有力的措施。现有建筑物抗震能力的评定是抗震加固必须采取的先行步骤。目前,抗震能力评定主要是按国家颁布的现行抗震鉴定标准进行,即采取“抗震鉴定标准法”。此法比较精细,但需按建筑物构造要求做构造措施评定,按抗震强度验算要求做分析评定。抗震强度验算需要受过专门训练的工程技术人员才能担当,而且需较长时间。一座城市房屋多 Seismic reinforcement of existing buildings and preparation of urban earthquake and disaster prevention plans are in progress. This is an extremely powerful measure to reduce earthquake disasters. The evaluation of the seismic resistance of existing buildings is an antecedent step that seismic strengthening must take. At present, the evaluation of seismic capability is mainly based on the current national seismic evaluation standards promulgated by the State, ie, the “Standard for Seismic Evaluation Standards”. This method is relatively fine, but it needs to be assessed according to the structural requirements of the building structure, and analyzed and evaluated according to the seismic intensity check requirements. Seismic strength verification requires trained engineers and technicians to take on it and it takes a long time. A lot of urban housing
