Outline of Final Research Achievements

The purpose of this research project is to quantitatively clarify the structural effects of the row of buildings that are often found in historic towns.　The following results were obtained.
1) Based on the results of a total survey conducted mainly in the historical towns of Kanazawa and Takaoka, as well as on the results of previous surveys, the extraction and distribution of adjacent conditions that can produce the effect of row houses were investigated, and the adjacent conditions that should be evaluated and verified were clarified.　2) Vibration experiments, seismic observations, and seismic response analysis were conducted on actual townhouse buildings to understand the analytical evaluation and actual behavior of townhouse buildings in rows.　3) Based on the results of the investigations and analyses, a seismic retrofitting method was studied.

Academic Significance and Societal Importance of the Research Achievements

本研究で対象としている歴史的なまちなみは全国に存在し、重要伝統的建造物群保存地区は105市町村で127地区選定されている（令和5年12月15日現在）。　歴史的なまちなみは、その文化的歴史的価値から保存・活用が望まれるものの、耐震性能に問題を抱えている場合も少なくなくない。本研究は、歴史的まちなみを建物単体ではなく地域全体に耐震化する手法を検討・提案するために実施したものであり、歴史的まちなみの存続に有用であると考える。
