摘要
通过平截面假定和对利用预应力碳纤维板加固可能产生的预应力损失进行分析,并从预应力碳纤维板加固混凝土T形梁后产生的破坏模式的角度去分析加固后混凝土T形梁的正截面抗弯承载力的计算方法,从而提出预应力碳纤维板加固混凝土T形梁正截面抗弯承载力的计算公式,并将理论计算值与试验值进行比较分析,发现两者之间有良好的吻合性.
Based on the plane section assumption, the calculation method of bearing capacity of normal section for reinforced concrete T-shaped beam was analyzed from the prestress loss and angle of failure mode which were produced by the reinforcement of prestressed CFRP plate on the reinforced concrete T-shape beam. Then, the calculation formula of bearing capacity of normal section for reinforced concrete T-shaped beam was proposed. The theoretical calculation and experimental results were compared, and there is a good agreement between them.
