【摘要】 通过延性系数指标来研究纤维布加固矩形截面混凝土连续梁的弯矩重分布能力,采用数值分析方法模拟纤维布加固矩形截面混凝土连续梁的弯矩重分布系数。研究发现,能量法计算的能量比可考虑纤维布加固T形截面混凝土连续梁的实际弯矩重分布能力,可利用弯曲刚度法分析纤维布加固T形截面混凝土连续梁截面弯矩重分布系数的演变过程。更多还原

【Abstract】 As for continuous concrete beams strengthened with fiber reinforced polymer(FRP), the ductility coefficient index was used to study its moment redistribution ability and meanwhile a numerical analysis method was adopted to fit the moment redistribution coefficient. It is found that the energy ratio calculated by using the energy method is considered with the actual moment redistribution capacity of continuous concrete beams strengthened with FRP and the flexural rigidity model can be used to analyze the evolution process of the moment redistribution coefficient of T-section continuous concrete beams strengthened with FRP.更多还原
