The purpose of this study is to evaluate the seismic performance and to develop seismic retrofitting methods for traditional wooden buildings with regional characteristics. First, a method for evaluating the seismic performance of mud walls with openings, which are often found in traditional wooden buildings, was studied. Next, the effects of building modeling methods and continuous columns on the seismic performance of traditional wooden buildings were investigated. Finally, we devel-oped a method to improve the strength of the wall clay, which greatly affects the seismic performance of mud walls, as a seismic retrofitting method for traditional wooden buildings.本研究は持続可能な都市・建築の構築に不可欠な環境制御をハニカム構造の機能特性を最大限に活用した種々の建材・構造の開発によって実現するものである．折紙工法は目的の仕様・形状からあらかじめ設計した展開図を基にシートにスリット・折線を導入し，折紙のように立体化する新しいハニカム製造法で，曲面パネルやセルに角度をつけた形状など，従来手法では不可能だった様々な形状のハニカム構造を安価に製造することが可能である．助成期間においては，ガラスやETFEフィルムなどの透明な表面材を貼った斜角型ハニカムパネルを開発し，パーティションを初めとする建材に応用するとともに，数値シミュレーションによって昼光利用，日射制御技術について研究した．This research aims to develop environmental the control technology, which is essential for building sustaina-ble cities and buildings, by developing various building materials and structures that take full advantage of the functional characteristics of honeycomb structures. The origami production method is a new honeycomb man-ufacturing method that introduces slits and fold lines into the sheet based on a crease pattern designed in ad-vance based on the desired specifications and shape, creating a three-dimensional shape similar to origami. It is possible to manufacture honeycomb structures of various shapes at low cost, which was not possible using conventional methods. During the grant period, we developed oblique honeycomb panels covered with trans-parent surface materials such as glass and ETFE film and apply them to building materials such as partitions, as well as research daylight utilization and solar radiation control technology through numerical simulations.
