In 2011, large earthquakes and natural disasters in Christchurch, New Zealand, and Japan demonstrated that existing structures are not yet sufficiently resilient to survive extreme events. One thing that was learned from both disasters but particularly from the New Zealand one is that immediately after a major event, there is significant confusion about which reinforced and prestressed concrete structures can be immediately returned to service, which should be temporarily closed and which should be permanently closed and demolished. Why this is of critical importance is that additional events, such as aftershocks, will occur after the initial event and can cause damaged buildings to collapse.

2011年，新西兰克赖斯特彻奇和日本发生的大地震和自然灾害表明，现有结构尚不足以在极端事件中幸存下来。从这两次灾难中，特别是从新西兰那次灾难中学到的一件事是，重大事件发生后，人们对哪些钢筋和预应力混凝土结构可以立即恢复使用，哪些应该暂时关闭，哪些应该永久关闭和拆除，存在着严重的困惑。这一点至关重要的原因是，在最初的地震之后，还会发生余震等其他事件，并可能导致受损的建筑物倒塌。
