| 中文摘要 | 本文旨在探討鋼筋混凝土剪力摩擦設計的安全性。本文採用Mattock之經驗公式,作為剪力摩擦應力之理論模式,並在考慮混凝土強度(??c)、鋼筋參數(pv??y)、剪力面尺寸、模式誤差及載重等皆為隨機變數的情形下,以蒙地卡羅法分析鋼筋混凝土的剪力摩擦強度及其破壞機率。研究結果顯示,當??c?280kg/cm2時,根據ACI規範進行剪力摩擦設計,會隨著??c的增加而使得剪力摩擦破壞機率降低,但對??c <280kg/cm2的情形,由於規範對於剪力摩擦強度另有上限值的規定,而使得其剪力摩擦破壞機率小於??c = 280kg/cm2時之破壞機率。本研究亦顯示,對剪力摩擦破壞機率而言,採用ACI規範附錄C之規定進行剪力摩擦設計會優於採用ACI規範主文之規定。 |
| 英文摘要 | The objective of this paper is to investigate the safety of shear friction design of reinforced concrete. The shear friction strength and the probability of shear friction failure of reinforced concrete are determined by Monte Carlo simulation technique. The strength of concrete (??c), the reinforcement parameter (pv??y), the dimensions of shear plane, the theoretical model error of shear friction stress and the loading are all considered as random variables. The theoretical model of shear friction stress is based on the empirical formula developed by Mattock. The results of this study show that for ??c?280kg/cm2, the probability of shear friction failure of reinforced concrete designed based on ACI Code decreases with the increase of ??c. Since the ACI Code specifies the upper limit for the shear friction strength, the probability of shear friction failure of reinforced concrete with ??c <280kg/cm2 is less than that with ??c = 280kg/cm2. The results of this study also show that the shear friction design based on the Appendix C of ACI Code is safer than that based on ACI Code. |
