The Heritage Hotel (formerly Old Government Buildings) is one of the architectural heritage icons of Christchurch, New Zealand. Seismic retrofitting was undertaken on the structure in 1995 to achieve the earthquake loading provisions of the 1992 standard for design loadings (NZS 4203:1992). This building is a distinguished 1909 unreinforced masonry Italian High Renaissance palazzo building. The retrofit work included the installation of new lateral load-resisting structural systems, refurbishment of individual building elements, and partial building demolition with a total cost of approximately NZ$3.75 million. Detailed observations following the 2010/2011 Canterbury earthquakes showed that the building was subject to only minor damage during the September 2010 earthquake, whereas the February 2011 event caused some damage to exterior stonework and flooding in the basement due to liquefaction. This damage was easily repaired, and the building was fully functional by September 2013. Reported herein are details showcasing the success of the seismic retrofit and post-earthquake performance observations.

Heritage Hotel酒店（原旧政府大楼）是新西兰基督城的建筑遗产标志之一。为了满足1992年设计荷载标准（NZS 4203：1992）的地震荷载规定，在1995年对该结构进行了地震加固。这座建筑是著名的1909年未经加固的砌体意大利高文艺复兴时期的宫殿建筑。改造工作包括安装新的抗侧向荷载结构系统，整修单个建筑构件以及部分拆除建筑物，总费用约为375万新西兰元。在2010/2011年坎特伯雷地震之后的详细观察表明，该建筑在2010年9月地震期间仅受到了轻微的破坏，而2011年2月的事件则由于液化对地下石料和地下室的洪水造成了一些破坏。该损坏易于修复，并且该建筑物在2013年9月之前已全部投入使用。此处报告的详细信息显示了地震改建和地震后性能观察的成功。
