[摘要]通过33根素混凝土圆柱的单独加固与复合加固的对比试验,对不同加固形式下素混凝土柱轴心受压下的极限承载力、应力应变关系以及延性等方面进行了研究和分析。结果表明, 复合加固素混凝土圆柱充分发挥了CFRP加固和增大截面加固的各自优点,有效地提高了圆柱的承载力和延性,同时大幅度降低了加固成本。

Abstract:Based on the test of 33 specimens, the bearing capacity, stress-strain relations and ductility of concrete circular columns reinforced with different forms are analyzed. The results indicate that, the load capacity and the ductility of the strengthened concrete circular columns with combination form increase significantly, and the strengthening cost reduces greatly.
