形態規制による建築利用可能空間と建築物のモデル化とそれを用いた形態規制評価: 住居系用途地域における斜線制限緩和と建物高さ規制の場合

摘要

First, mathematical model of possible building space under the setback regulations of Japan Building Standard Law is developed. Second, mathematical model of building form is also developed according to the possible building space, which utilizes the maximum floor area- Third, in order to study the effects of the ease of setback regulation and building height control some simulations are done using these models for a case of residential land-use zoning district in Kanazawa City, As a result of this study quantitative relationship between these regulations and building forms such as total floor area and the maximum building height are clarified and it is also affirmed that the building height control in residential land-use zoning districts by the ordinance does not practically affect the floor area utilization possibility under the land-use zoning.%本論文では、建築基準法における斜線制限を反映した建築利用可能空間と、その空間内に存在する建築物をモデル化し、それによつて斜線制限緩和および各種の上乗せの形態規制のーつとして建物高さ規制による建築物の形態への影響について明らかにし、評価してきた。その内容は以下のようにまとめられる。斜線制限緩和の影饗をみるにあたって、道路斜線適用限界距離の設定による緩和と壁面後退による緩和の2種類について分析を行つた。
