| 摘 要： | 采用在钢筋混凝土框架连续梁的正弯矩区粘贴碳纤维复合材料的方法,对钢筋混凝土连续梁正负弯矩区强度互补进行加固对比试验,并用ANSYS软件有限元仿真分析对试验结果进行了验证.结果表明,通过加固连续梁的正弯矩区抗弯强度可以提高负弯矩区的承载能力,并且对构件的抗裂性能和刚度均有补强作用.

| Abstract: | We use the method that improve the bearing capacity of the negative moment through reinforced the positive moment by CFRP for reinforced concrete frame beam.Carry comparative trial on the positive and negative bending moment supplementary reinforcement for three reinforced concrete continual beam,analysis and obtain the test result with the ANSYS software.The results show that the bearing capacity of the negative moment is improved through reinforced the positive moment,and crack resistance and stiffness of the components are reinforced simultaneously. |
