建物の耐震性評価を目的とするRC壁の気密性能評価

摘要

This paper focuses on the airtight performance of reinforced concrete (RC) walls used as exterior walls in a typical residential building(prototype building) in Japan. Air leakage tests were performed using two full scale RC wall specimens subjected to shear damage. The airtight performance of RC walls was evaluated using a fan pressurization method for air leakage. Furthermore, this paper evaluates a limit corresponding to function maintenance of the prototype building based on a design limit of the C value and the air leakage test results.%本研究では，地震により被災したRC建物の気密性能に基づく住機能維持限界を評価する案を提案し，これを実現すべく RC壁の損傷(ひび割れ）と気密性の関係を載荷と気密測定を繰り返す実験より取得した，また，実験結果に基づきプロトタイプ建物について住機能維持限界を試算した.以下に本稿の内容をまとめる.1)被災RC建物を対象に，気密性能C値の制限に基づいて住機能性を維持できる限界を評価する一^3の案を示した.
