In order to make plans to retrofit refuges, the database of houses and refuges are arranged, and relation between the acceleration at bedrock and the number of refugees are studied. Then the capacity of refuges, the limit bedrock acceleration for capacity of refuges and the number of refugees over capacity of refuges in Nagoya are analyzed. Based on the results from these analyses, the effects of retrofit refuges are estimated using 240gal(2E) at bedrock as the target of maximum acceleration of an earthquake, and 20% as the target of damage ratio of refuges. The amount of capacity of refuges to increase is also estimated because of the existence of upper limit of retrofit effects caused by lack of existing refuges.
