In Japan, a lot of building and infrastructure have been
experienced severe earthquake disaster since the dawn of history. Recently,
there are many discussions about repairability and recovery for these damaged
building structures, in particular, after 2011 Great East Japan Earthquake.
There has been focused on the new keyword “Resilience”, which presents therevival potential or function maintenance of damaged structures and Bruneau and
Reinhorn have mentioned the concept of structural resilience, and high
resilience system is as follows:reduced failure probabilities,reduced
consequences from failures, in terms of lives lost, damage, and negative
economic and social consequences,reduced time to recovery.
The technical guideline has been published to repair the
various kinds of structures in Japan. Particularly for steel structures, it
suggests a repairing method based on the past experimental researches, however
the number of such past researches was restricted. And also, few past research
on repairability and recovery of steel structures limit to Japan have been
conducted.
