摘要
基于已有的FRP加固梁的抗弯试验,推导了FRP侧贴和底贴加固梁的正截面受弯承载力计算公式,并对侧贴与底贴的加固效果进行了对比分析,结果表明,FRP侧贴加固梁的开裂荷载优于FRP底贴加固梁,而FRP侧贴加固梁的极限承载力稍低于底贴加固梁。
Based on the existing flexural experiment on RC beams strengthened with FRP, the calculation formula of normal section flexural capacity of the beam strengthened with FRP bonded on the side and bottom was deduced, and the rein- forcement effects of side bonding and bottom bonding were compared and analyzed. The result indicates that, the cracking load of RC beams strengthened with side bond- ed FRP is superior to that strengthened with bottom bonded FRP, whereas the ultimate bearing capacity of the former is slightly lower than the later.
