Outline of Final Research Achievements

The objective of study is to develop the seismic upgrade technique for existing crucial RC buildings such as governmental office and gymnasium and following items is carried out;
(1) propose of damage evaluation method and seismic upgrade techniques to mitigate severe damage for vulnerable elements, (2) evaluation of seismic upgrade effect for frame level, (3) application of seismic upgrade method for building with post-earthquake functional use
As a result of these investigations, each technique to mitigate severe damage under severe earthquake for RC non-structural walls, joints between RC column and steel roof and concrete piles is developed and the effectiveness of each technique is confirmed.　Moreover seismic upgrade method to guarantee the post-earthquake functional use of existing crucial building is proposed and some evaluation examples to verify the method are shown.
