摘要
对15根玻璃纤维布加固的钢筋混凝土梁进行了试验研究。试验结果表明,玻璃纤维布加固的钢筋混凝土梁抗弯承载力显著提高,加固效果明显,但要有足够的粘贴长度以避免发生剥离破坏。
The results of experimental studies concerning the flexural strengthening of reinforced concrete beams by the external bonding of high-strength, lightweight glass fiber reinforced plastic (GFRP) sheets to the tension face of the beam were summarized. Fifteen beams were tested experimentally to evaluate the strength enhancement provided by the GFRP sheets. GFRP parameters would markedly influence the load resistance capacity and the failure mechanisms. To eliminate the deboning failure, it is proposed that the bonded length should be sufficient.
