摘要

本研究以蒙地卡羅法探討鋼筋混凝土懸臂梁之握裹破壞機率。研究結果顯示，對於根據現行ACI規範設計之鋼筋混凝土懸臂梁，其握裹破壞會較撓曲破壞更容易發生。根據Darwin等人(2005)之建議進行握裹設計之鋼筋混凝土懸臂梁其握裹破壞機率會低於根據現行ACI規範進行握裹設計之鋼筋混凝土懸臂梁。

並列摘要

The failure probabilities in flexure and bond of reinforced concrete cantilever beams have been investigated in this study by Monte Carlo technique. For beams designed according to the ACI Code, bond failures are more probable than flexural failures. The failure probabilities in bond of beams designed according to the recommendations of Darwin et al. are lower than those designed according to the ACI Code.
