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，基督城，新西兰和日本的大地震和自然灾害表明，现有的结构尚未足够弹性，无法在极端事件中生存。 从两种灾难中学到的一件事，尤其是从新西兰那里学到的一件事是，在重大事件发生后，立即使加固和预应力的混凝土结构可以立即返回服务，这引起了极大的困惑，应暂时关闭，这些结构应暂时关闭，应永久关闭并拆除。 为什么这至关重要的是，其他事件（例如余震）将在初次事件发生后发生，并可能导致建筑物崩溃。
