ABSTRACT

The seismic vulnerability assessment of buildings in historic city centres is the first step to mitigate the possible damage, to prevent heritage losses and to preserve their historical identity. In this paper, the analysis is focused on the residential buildings of “Ground Zero Area” in El Cabanyal. This unique quarter of Valencia, once a fishermen’s settlement, has a strong village-like identity and heritage value. Swallowed up by an expanding city centre and threatened by a poor redevelopment plan, which caused its degradation, its rehabilitation is nowadays the object of a new protection plan. The seismic vulnerability of the residential buildings has been assessed using the Vulnerability Index Method, obtaining a global damage index, and the equivalent built area expected to be destroyed. Results, implemented in a GIS environment, revealed that, due to the high vulnerability, many of the analysed listed buildings will be significantly damaged. A new detailed analysis is recommended, to define intervention and retrofitting criteria to improve their seismic response, preserving the architectural heritage and defending the unique identity of El Cabanyal.

摘要

历史城市中心建筑物的地震脆弱性评估是减轻可能的损害、防止遗产损失和保护其历史特征的第一步。在本文中，重点分析了El Cabanyal“零地区”的住宅建筑。这个独特的瓦伦西亚区曾经是渔民聚居地，具有强烈的乡村特色和遗产价值。被不断扩大的市中心吞没，并受到糟糕的重建计划的威胁，导致其退化，如今它的修复成为新保护计划的目标。住宅建筑的地震脆弱性已使用脆弱性指数方法进行评估，获得全球损害指数，以及预期被摧毁的等效建筑面积。结果，在 GIS 环境中实施，透露，由于高度脆弱，许多被分析的列入名单的建筑物将受到严重破坏。建议进行新的详细分析，以确定干预和改造标准，以改善其地震反应，保护建筑遗产并捍卫 El Cabanyal 的独特身份。
