Resilient Reinforced Masonry Buildings: Risk-based System-level Seismic Design Approaches

最近世界各地的地震表明，尽管现代建筑设计规范在限制新建筑死亡人数方面基本上取得了成功，但它们在限制社会经济成本方面几乎没有做什么。智利（2010年）、新西兰（2011年）和日本（2011年）的地震都造成了严重的损失，动摇了国家经济和心理。正如受灾社区的人们所经历的那样，满足建筑规范意图的建筑物在地震后可能不安全，拆除这些建筑物可能比修复它们更经济。根据加拿大保险局2013年委托的一份报告，加拿大大部分建筑物将在大地震中遭受严重破坏或完全倒塌。预计魁北克市-蒙特利尔-渥太华走廊的大地震将造成600多亿加元的损失，如果不列颠哥伦比亚省发生大地震，将造成近750亿加元的损失。拟议研究计划的三个相互关联的重点领域旨在开发弹性配筋砌体（RM）建筑系统，这些系统将在重大地震事件后受到有限或易于修复的损坏。

Recent earthquakes worldwide have demonstrated that, although modern building design codes have generally succeeded in their intent of limiting fatalities in new construction, they have done little to limit socioeconomic costs. The earthquakes in Chile (2010), New Zealand (2011), and Japan (2011) all caused severe losses that shook the national economies and psyches. As people in affected communities have experienced, buildings that satisfy the intent of the building code may not be safe to occupy after the earthquake, and it may be more economical to demolish these buildings than to repair them. According to a 2013 report* commissioned by the Insurance Bureau of Canada, a substantial portion of Canada’s building stock will experience severe damage or complete collapse during a major earthquake. It is expected that a major earthquake in the Quebec City-Montreal-Ottawa corridor will result in losses of more than C$60 billion, and nearly C$75 billion if a major earthquake were to occur in British Columbia. The three interrelated focus areas of the proposed research program are designed to develop resilient reinforced masonry (RM) building systems that will experience limited or easy-to-repair damage following major seismic events.
