After the 2016 New Zealand Kaikoura Earthquake, the absence of information about the state of buildings in Wellington proved to be a source of significant policy uncertainty. Authorities did not know what damages to expect and therefore how to react, and policies needed to be formulated without a clear quantification of the risks. Moreover, without detailed knowledge of the existing buildings, it was difficult to assess what the available legal and regulatory tools can achieve and choose among them. We describe the creation of a building inventory database for Wellington initiated by the authors. This database aims to assist the generation of research on the risks, impacts, and viable solutions for reducing future seismic risk in Wellington’s central business district (CBD). The database includes structural, economic, and market information on virtually every significant building in the CBD. Its primary purposes are: to collate and provide the best available information about the expected seismic performance of the existing building stock; to assess the impact of possible multiple building failures due to a seismic event; to describe a viable cost-effective path for seismic retrofitting; and to inform the design of a regulatory structure that can facilitate this resilience-building agenda.

震源城市建筑库存的地震政策,运营和研究用途

在2016年纽西兰凯库拉大地震之后,惠灵顿缺乏有关建筑物状态的信息被证明是重大政策不确定性的根源。当局不知道预期会有什么损害,因此如何应对,在没有明确量化风险的情况下需要制定政策。此外,如果没有对现有建筑物的详细了解,很难评估可用的法律和监管工具可以实现什么并在其中进行选择。我们描述了作者发起的惠灵顿建筑存量数据库的创建。该数据库旨在帮助研究有关风险,影响和可行解决方案的研究,以减少惠灵顿中央商务区(CBD)的未来地震风险。该数据库包括结构,经济,以及几乎所有CBD重要建筑物的市场信息。其主要目的是:整理并提供有关现有建筑材料的预期抗震性能的最佳可用信息;评估由于地震事件可能造成的多个建筑物倒塌的影响;描述一条可行的,具有成本效益的抗震改造路径;并告知设计可以促进此弹性建设议程的监管结构。
