Abstract

Surveys conducted in the aftermath of recent earthquakes have shown that the structural and anti-seismic performances of historical masonry churches are related not only to structural damages and masonry quality but also to other key features such as effectiveness of connections, damages of wooden elements or criticalities related to humidity. Technical and scientific communities are interested in developing or improving existing procedures for the fast-visual survey and diagnostics in order to measure and analyze all the parameters affecting the building performance. In this paper a new procedure, that can be implemented in a Decision Support System (DSS) based on the Analytic Hierarchy Processes (AHP), is developed to perform a rapid visual survey and diagnostics of masonry building through a set of condition ratings. The originality of the presented work is fourfold: 1) the AHP allows to include in the analysis qualitative and quantitative data such as the quality of masonry and connections effectiveness; 2) the proposed survey and diagnostics performed by suitable condition ratings allow an extensive application in order to identify the most damaged buildings that require more detailed structural investigations; 3) the proposed AHP-based approach is integrated in a DSS to provide a powerful computerized tool, useful to large scale data acquisition; 4) the comparison with a standard diagnostics is performed to validate the procedure and emphasize the advantages of the novel diagnostics.
结合现代信息技术的基于层次分析法的历史砖石教堂诊断方法
在最近的地震之后进行的调查表明,历史砌体教堂的结构和抗震性能不仅与结构损坏和砌体质量有关,还与其他关键特征有关,如连接的有效性、木制构件的损坏或与湿度有关的临界性。技术和科学界对开发或改进现有的快速视觉调查和诊断程序感兴趣,以便测量和分析影响建筑性能的所有参数。本文提出了一种基于层次分析法(AHP)的决策支持系统(DSS)的新方法,通过一组状态等级对砌体建筑进行快速的视觉调查和诊断。所提出的工作的独创性在于四个方面:1)AHP允许在分析中包括定性和定量数据,如砌体质量和连接有效性;2)通过适当的状况评级进行的拟议调查和诊断允许广泛应用,以确定需要更详细的结构调查的受损最严重的建筑物;3)将基于层次分析法的方法集成到决策支持系统中,为大规模数据采集提供了强大的计算机化工具;4)与标准诊断进行比较,以验证程序并强调新诊断的优点。

期刊介绍: From the outset, the aim was to initiate an open and continuous exchange of information among different countries, thus prompting the creation of an international Scientific Committee. Representatives of the major Italian and foreign institutes interested in archaeological computing agreed to become members. A qualified Editorial board also assures a continuous flow of information and a profitable exchange of data. The journal covers three distinct parts. The first considers methodological approaches: it collects articles concerning theoretical aspects of archaeological computing as well as reports on programmes conducted by dedicated international institutions. The main section contains articles on various computer applications, such as databases, Geographical Information Systems, quantitative methods, expert systems, computer graphics, image processing, multimedia and web tools. A section is also dedicated to the automatic processing of documentary sources. The third aspect of the journal is characterised by book reviews and bibliographic news, with the aim to provide readers with an up-to-date source of documentation. Special thematic issues and Conference Proceedings have also been included.
