鋼筋混凝土梁扭力強度評估方法之比較

Evaluation on Torsion Strength of Reinforced Concrete Beam using Different Method

摘要


本研究利用薄管立體桁架類比理論、斜彎矩理論、變角空間桁架模型、中國大陸規範及軟化桁架模式,評估鋼筋混凝土梁之扭力強度,並與文獻上已發表之實驗相比較,以驗證其適用性;不同評估方法各有其不同之假設,因此會影響評估之結果。研究結果顯示,軟化桁架模型所得之平均值較接近實驗值,且變異係數最小。

並列摘要


This paper evaluate on torsion strength of reinforced concrete beam by using thin-walled tube theory, skew-bending theory, GBJ 10-89 in China, and soften truss model. And, that solution will reveals to experimental data. Above-mentioned, the different evaluations have the different assumption effect in result. The result of predictions shows that the soften truss model proposed by Hsu (1988) reveals close correlation to experimental data.
