| 摘 要： | 以一座主跨径为20m的5孔钢筋混凝土简支梁桥为实例,基于相似理论按照几何尺寸比CL=1/4设计了T形主梁的9片缩尺模型梁,试验共分为3组,探讨了不考虑二次受力情况(试验2)与考虑二次受力情况(试验3)下对梁体进行贴BFRP布加固后构件的极限承载力、裂缝开展、BFRP布应变及最终的破坏模式等相关力学特性,并与未加固对比梁...

| Abstract: | Taken a reinforced concrete beam bridge which has 20 m main span as an example,based on similarity theory,9 scale model beams of T-beam were designed in accordance with CL=1/4.The test was divided into three groups: test I: contrast beams without reinforcement,test II: reinforced beams without considering the secondary load,and test III: reinforced beams considering the secondary load.The ultimate load,crack propagation,strain of basalt fiber reinforced polymer(BFRP) sheet and the ultimate failure mode of t... |
