建筑物震害评估是城市抗震防灾规划的一项重要工作。为快速评估城区建筑物的抗震能力,提出了面向抗震防灾规划的多级震害评估方法,即除个别重点建筑采用弹塑性分析法外,将城区建筑分为重要建筑和一般建筑,分别采用模糊震害指数法中的详细表格评估法和简化表格评估法,快速获得各建筑在不同烈度下的破坏等级,以评估整个城区的建筑物抗震能力。最后,以沭阳县抗震防灾规划编制工作中的建筑物震害评估为例,介绍了该方法在实践中的应用。
Earthquake damage assessment of buildings is an important task of urban earthquake disaster prevention planning. In order to quickly evaluate the seismic capacity of urban buildings, a multi-level earthquake damage assessment method for earthquake-resistant and disaster-prevention planning is proposed. In addition to using the elasto-plastic analysis method for some key buildings, the urban buildings are divided into important buildings and general buildings, The detailed table evaluation method and the simplified table evaluation method in the fuzzy earthquake damage index method can quickly obtain the damage grades of various buildings under different intensities so as to evaluate the seismic capacity of buildings in the entire urban area. Finally, taking the seismic hazard assessment of buildings in the preparation of earthquake prevention and disaster prevention planning of Shuyang as an example, the application of this method in practice is introduced.
