| 摘 要： | 对10根粘贴不同长度和厚度玻璃钢板加固的混凝土梁进行静载试验研究,探讨玻璃钢板尺寸对加固混凝土梁加固效果的影响,试图找到在满足加固要求的前提下的最佳玻璃钢板粘贴尺寸,为合理地对外贴玻璃钢板等复合材料加固混凝土梁进行设计提供了试验数据.结果表明,玻璃钢板粘贴尺寸不同,加固混凝土梁的开裂弯矩、极限弯矩、跨中挠度、跨中应变均有较大变化.通过分析这些变化,推算出玻璃钢板最佳粘贴尺寸.

| Abstract: | A dead-loading test is performed to discuss the effect of dimension of glass fiber reinforced plastic(GFRP)on ten reinforced concrete beams strengthened by different length and thickness of GFRP,and trying to discover the most optimal dimension with their strength enough,which is used for providing test datum for the beam's design.The results of test show that the cracking moment,the ultimate bearing moment,the deflection at midspan and the strain at midspan vary considerably as the length and thickness of ... |
