鋼と木質材料の複合構造システムの構法成立の可能性

摘要

Trimming thinned woods is one of the methods to plan growth of the forest. In the field of building structure, it is necessary to use thinned woods as timber positively. However, timber is too weak to apply to the large-scale buildings. Research and development of a building system to use timber are demanded. Authors consider possibility that a building system is composed of steel and timber considering the global environment. The building system of composite steel-timber structure type is classified and its characteristic is shown. Requirement performances of each type are evaluated to provide the building system. Based on an evaluation result of requirement performance, the specific example called CSTS (Composite Steel-Timber Structure) is shown and the details of CSTS are considered.%建築躯体を造るためには多量の资源を消费し，多量のCO_2を排出し，廃棄時には多量の廃棄物が出ることを考えると，建築構造分野では建築デザインや建築環境の分野とは異なるアプローチが求められる。著者らは，「地球環境に配慮した建築構造」をコンセプトに，「長寿命化」を第一に考え，さらに意匠的，経済的，社会的な要因により，やむなく解体しなければならない場合を念頭に「リユース」を想定した，「サステナブルビル構造」を研究開発し，その振興に努めてきた。
