[摘要]通過33根素混凝土圓柱的單獨加固與復合加固的對比試驗,對不同加固形式下素混凝土柱軸心受壓下的極限承載力、應力應變關(guān)系以及延性等方面進行了研究和分析。結(jié)果表明, 復合加固素混凝土圓柱充分發(fā)揮了CFRP加固和增大截面加固的各自優(yōu)點,有效地提高了圓柱的承載力和延性,同時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.
Keywords:combination strengthened; circular column; carbon fiber reinforced plastic; axial compressed; increasing section
