Abstract

本報告では, 超高強度繊維補強コンクリートを用いたプレストレストスラブの耐火性能を記述する。載荷加熱試験を実施した結果, 緊張材の高温時特性を評価・把握することで, 耐火時間を推定できることが分かった。さらに, プレストレストスラブを建築構造物に適用し, その概要を述べる。

The paper first summarizes the findings from loaded heating tests of prestressed slabs made of ultra-high strength fiber reinforced concrete (UFC). Based on the test results, a design procedure was developed for estimating the fire resistance of UFC slabs, taking into account the temperature rise and loss of strength of prestressing steel, both induced by heating during fires. Furthermore, the report provides a brief overview on the process of fabrication and installation of the UFC slabs for the enlargement and refurbishment project of an existing office building in Yokohama, Japan.
