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.

该快速反应研究（RAPID）奖项的目的是收集2011年2月新西兰基督城地震中关于无钢筋砌体（URM）结构性能的易腐数据，这些结构已采用粘合剂锚固件进行改造。 这种锚杆用于将楼板或屋顶横隔梁连接到砌石墙或女儿墙上。在美国和新西兰，使用这些锚固件的墙-横隔板连接改造是最常见的地震修复技术。 美国和新西兰的城市资源管理建筑存量，包括未经改造和经过改造的建筑，有许多相似之处。在为期28天的现场工作期间，将尽可能多地从基督城地区59座经过改造的URM建筑以及类似的未改造建筑中收集易腐数据。 这些数据将被用于后续研究的URM建筑库存在美国的这种改造策略。这一活动将扩大目前对城市资源管理建筑物易受地震影响的认识。通过关注URM建筑物的粘合剂锚改造的观察性能，收集的数据及其分析将提供增强的评估方法，用于评估URM建筑物的地震修复技术。 目标是提高URM建筑的地震安全性，URM建筑在美国广泛建造，是最容易受到地震影响的建筑类型之一。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。
