对钢筋砼梁作扭转试验,直到破坏。然后用粘结剂把钢板粘结在梁的一侧,予以修补。修补后的梁承受同样荷载时,其强度比原来的梁提高33%。所有修补的梁都是弯曲破坏,而不是扭转破坏,而且挠度比原来的梁小25%。在试验前外部先用钢板增强的加固梁,其强度提高43%,而且也是弯曲破坏。 The torsion test was performed on the reinforced concrete beam until it was destroyed. Then glue the steel plate to one side of the beam and fix it. When the repaired beam receives the same load, its strength is 33% higher than that of the original beam. All repaired beams are bending damage, not torsional damage, and the deflection is 25% smaller than the original beam. Before the test, reinforcement beams reinforced with steel plates on the outside were used, their strength was increased by 43%, and they were also bent and destroyed.
