东京是世界上最大的城市之一，也是日本的首都，日本是一个地震多发的国家。日本人口及其大部分功能高度集中在东京。未来发生的日本7级以上的大地震对东京造成的损失估计极高。由于地震本身和地震后的火灾，伤亡人数可能超过2万人。因长途通勤线路故障而无法回家的工人、学生和其他人的滞留人数将高达800万。可能倒塌或烧毁的建筑物估计有61万座。包括生产率和服务业下降的影响在内，经济损失可能高达95万亿日元，几乎相当于日本的年度一般账户预算[1]，[2]。世界上有许多大城市和其他社会，像东京一样，很容易受到大地震的灾难性破坏。先进的现代城市和社会必须更具可持续性和弹性，以减少地震破坏，这可能与上述东京的情况相当。为了实现这一目标，结构必须更加可靠。
Tokyo, one of the largest cities in the world, is the capital of Japan, a heavily earthquake-prone country. The Japanese population and much of its functionality are highly concentrated in Tokyo. The estimated damage to Tokyo as a result of future large earthquakes with a magnitude greater than the Japanese scale 7 is extremely high. The number of casualties could exceed 20 000 due to both the shaking itself and post-earthquake fires. The number of stranded workers, students, and others unable to return home due to failures in long-distance commuting lines would be as high as 8 million. The number of buildings likely to collapse or burn is estimated at 610 000. The economic loss, including the effect of the decrease in productivity and services, could be as high as 95 trillion yen, which is nearly equivalent to the Japanese annual general account budget [1],[2].Like Tokyo, many large cities and other societies exist in the world that are vulnerable to catastrophic damage from large earthquakes. Advanced modern cities and societies must be more sustainable and resilient in order to reduce earthquake damage, which may be comparable to that described above for Tokyo. To achieve this goal, structures must be more reliable.
