通过6根矩形截面钢筋混凝土梁静力试验,考察了不同玄武岩纤维布粘贴层数下,加固梁的承载能力及破坏模式,试验表明在钢筋混凝土梁受拉区粘贴玄武岩纤维布可有效提高既有损伤钢筋混凝土梁的抗弯性能。采用ANSYS软件对BFRP布加固既有损伤钢筋混凝土梁进行数值模拟,并与试验结果进行对比,验证了应用ANSYS有限元软件对BFRP布加固既有损伤钢筋混凝土梁进行数值模拟的有效性。
Through the static tests of 6 rectangular RC beams, the carrying capacity and failure mode of the reinforced beams under different layers of basalt fiber cloth were investigated. The experiment shows that the basalt fiber cloth can be effectively bonded in the tension zone of the RC beams, Bending resistance of concrete beam. ANSYS software is used to simulate the existing damaged RC beams with BFRP sheets and compared with the experimental results. The effectiveness of the finite element software ANSYS is verified by numerical simulation of the existing damaged RC beams with BFRP sheets.
