CFRP筋混凝土梁正截面承载力设计建议

Design Suggestion for Normal Section Ultimate Strength of the Reinforced Concrete Beams with Carbon Fiber Sheet

CFRP加固混凝土结构技术具有诸多优点,目前在国内外得到广泛的运用.国外对CFRP筋混凝土梁正截面承载力公式制定了规范,而我国还没有对CFRP筋混凝土梁正截面承载力制定专门的规范.本文在试验基础上,参考国外的有关资料,提出了CFRP筋混凝土梁正截面承载力设计建议.结果表明本文的承载力建议值与实验结果吻合较好,能较准确地计算CFRP筋混凝土梁的承载力,为工程设计提供了参考.

At present, CFRP strengthened reinforced concrete has been applied more and more widely in China because of many advantages. Normal section ultimate strength has been formulated for the specifications and standards to the CFRP reinforced concrete beams in overseas,but not in our country. Based on the experiment and referring to the overseas,this paper puts forward the de- sign suggestion for normal section ultimate strength of the CFRP reinforced concrete beams. The results show that the agreement between the suggested result the experimental result is satisfactory ,and that the suggested formula can accurately calculate the ultimate strength of the CFRP reinforced concrete beams. The result of this paper has reference value for engineering design.
