在設計混凝土結構不連續區域時壓拉桿模型是相當有用的工具,儘管壓拉桿模型已被納入美國AASHTO-LRFD橋樑規範與ACI 318-02規範附篇A之中,但兩規範中關於壓桿混凝土之有效抗壓強度條款仍存在部分爭議。本研究自文獻蒐集237支托架實驗數據檢驗兩規範之壓拉桿模型設計條款,實驗資料比對結果顯示,斜壓桿混凝土軟化係數會隨剪力跨深比及混凝土強度提高而遞減,而ACI方法和傳統托架設計方法未能考慮這兩個參數之影響,但傳統設計方法仍是保守的。本文建議採AASHTO規範之軟化係數公式並增加下限值0.45,可以提升設計經濟性及評估準確性。
Strut-and-tie modeling is a valuable tool for designing discontinuity regions of concrete structures. Although the strut-and-tie modeling has been incorporated into the AASHTO-LRFD Bridge Specifications and Appendix A of the ACI 318-02 Building Code, there is still some debate over the effective compressive strength of a strut between these two different design provisions. This study calibrated both design provisions using experimental results from 237 tests of corbels found in the literature. Based on the experimental verification, the strength reduction coefficient for concrete in the diagonal strut was found to decrease with the increase of the shear-to-span ratio and the compressive strength of concrete. These two parameters were not considered in the ACI and traditional corbel design methods, but traditional corbel design methods were conservative. A modification to the AASHTO provisions on the strength reduction coefficient was proposed in this paper which would improve the efficiency and accuracy in design with Strut-and-Tie Modeling.
