The objective of this paper is to demonstrate how assessment of seismic vulnerability can be effective in protection against earthquakes. Findings are reported from a case study in a densely populated urban area near an active fault, utilizing practical methods and exact engineering data. Vulnerability factors were determined due to technical considerations, and a field campaign was performed to collect the required data. Multi-criteria decision making was carried out by means of an analytical hierarchy process including a fuzzy standardization. Earthquake scenarios were applied through an implicit vulnerability model. GIS was utilized and the results were analyzed by classifying the state of vulnerability in levels as very low, low, moderate, high, and very high. Seismic resilience was evaluated as vulnerabilities below the moderate state, being about 40% in an intensity of 6 Mercalli and less than 10% in 10 Mercalli. It is concluded that seismic resilience in the area studied is not acceptable, the area is vulnerable in the expected scenarios, and due to the high seismicity of the region, proper crisis management planning is required in parallel with attempts toward retrofitting. In this regard, an emergency map was developed with reference to the assessed vulnerabilities.

通过基于GIS的建筑物脆弱性评估进行实用的抗震能力评估和危机管理规划

本文的目的是演示如何评估地震脆弱性才能有效地抗震。利用实际方法和精确的工程数据,从一个活动断层附近人口稠密的城市地区的案例研究中报告了发现。出于技术考虑确定了脆弱性因素,并开展了野战活动以收集所需数据。多准则决策是通过包括模糊标准化在内的分析层次过程来进行的。通过隐式漏洞模型应用了地震场景。利用了GIS,并通过将脆弱性状态分为非常低,低,中,高和非常高的级别对结果进行了分析。抗震能力被评估为低于中等状态的脆弱性,在6个Mercalli强度下约为40%,在10个Mercalli强度下不到10%。结论是,所研究区域的地震复原力是不可接受的,在预期的情况下该区域是脆弱的,并且由于该区域的高地震活动性,在进行改造的同时还需要适当的危机管理计划。在这方面,参照评估的脆弱性制定了应急图。
