施工中の吊荷落下を受ける鉄筋コンクリート床スラブの損傷性状に関する研究（その２）：デッキプレートを用いた破片飛散防止工法の飛散判定方法

抄録

This study proposes a simple prediction method to judge whether deck plates detachment and debris scattering occur in reinforced concrete slabs subjected to accidental falling-object impact during construction. The method targets a previously proposed anchorage system with a folded deck-plate edge embedded in concrete. Finite-element analysis of scaled impact tests showed that concrete and reinforcing bars dominated energy absorption, whereas the deck plate contributed only about 5%. A penetration-depth equation was derived from energy balance, and detachment was judged from the geometric relationship between penetration depth and deck-plate withdrawal. The method accurately predicted detachment without further experiments or numerical analysis.
