RAPID: Data Collection on the Performance of Adhesive Anchor Retrofits in Unreinforced Masonry Buildings during the February 2011 Christchurch, New Zealand Earthquake

这项快速反应研究(RAPID)奖的目的是收集2011年2月新西兰克赖斯特彻奇地震中易腐烂的数据，这些数据是关于安装了粘结剂锚的未加固砖石结构(URM)的性能。这种锚杆用于将地板或屋顶横隔板连接到砖墙或护墙。在美国和新西兰，使用这些锚杆进行墙体-横隔板连接改造是最常见的抗震修复技术。美国和新西兰的URM建筑存量，包括未加装和加装的建筑，都有许多相似之处。在28天的实地工作期间，将尽可能多地从克赖斯特彻奇地区59座经过翻新的城市轨道交通建筑以及类似的未翻新建筑中收集易腐烂的数据。这些数据将用于对美国URM建筑库存的这一翻新战略的后续研究。这项活动将扩大目前对URM建筑对地震影响的脆弱性的理解。通过对采用粘结式锚杆加固的URM建筑的观测性能进行分析，收集到的数据及其分析将为评估URM建筑的抗震修复技术提供更好的评估方法。目标是提高URM建筑的抗震安全性，URM建筑在美国被广泛建造，也是最容易发生地震的建筑类型之一。这项研究的结果将广泛分发给地震工程界，包括负责更新和改进国家抗震设计规定的组织。

The objective of this Rapid Response Research (RAPID) award is to collect perishable data from the February 2011 Christchurch, New Zealand earthquake on the performance of unreinforced masonry (URM) structures that had been retrofitted with adhesive anchors. Such anchors are used to connect floor or roof diaphragms to masonry walls or parapets. Wall-to-diaphragm connection retrofit using these anchors is the most common seismic rehabilitation technique used in both the U.S. and New Zealand. The URM building stocks in the United States and New Zealand, including both unretrofitted and retrofitted buildings, share many similarities. Perishable data will be collected from as many of the 59 retrofitted URM buildings in the Christchurch area, as well as from comparable unretrofitted buildings, as is possible during the 28-day duration of the field work. This data will be used for follow-on research of this retrofit strategy for the URM building inventory in the United States. This activity will expand current understanding of URM building vulnerabilities to earthquake effects. By focusing on the observed performance of URM buildings with adhesive anchor retrofits, the data collected and its analysis will provide enhanced assessment methods for evaluating seismic rehabilitation techniques for URM buildings. The goal is to advance the seismic safety of URM buildings, which are widely constructed in the U.S. and one of the most seismically vulnerable building types. The results of this research will be widely distributed to the earthquake engineering community, including organizations responsible for updating and improving national seismic design provisions.
