| 中文摘要 | 本文旨在探討鋼筋混凝土托架的剪力破壞機率。本文採用軟化壓拉桿模型來計算鋼筋混凝土托架的剪力強度,並在考慮混凝土強度、鋼筋的強度、斷面的尺寸、模型之不確定性及載重等皆為隨機變數之情形下以蒙地卡羅法分析鋼筋混凝士托架的剪力破壞機率。研究結果顯示,根據ACI規範設計的托架,其剪力破壞機率皆低於1×10-3,且剪力破壞機率會隨著混凝土抗壓強度的提高及剪力跨度與有效深度比值的減小而降低。 |
| 英文摘要 | This paper aims to investigate the probability of shear failure of reinforced concrete corbels by the Monte Carlo technique. The shear strength of reinforced concrete corbels is calculated by softened strut-and-tie model. The random variables considered in this study are the strength of concrete, the strength of reinforcing steel, the dimension of cross section, the model uncertainty and the loading. The result of this paper show that the probability of shear failure of reinforced concrete corbels designed using the ACI Code is below 1×10-3. It is also found that the probability of shear failure decreases with the increase of the compressive strength of the concrete and decreases with the increase of the shear span-to-depth ratio. |
