| 摘 要： | 为研究碳纤维布加固预应力混凝土空心板在近似均布载荷作用下的受力性能和加固效果,通过8块按工程实际尺寸设计制作的预应力混凝土空心板试件,在近似均布载荷作用下的试验,研究不同的碳纤维布粘贴方式及粘贴数量,对碳纤维布加同预应力混凝土空心板受力性能和加固效果的影响:阐述了加固后试件承载力提高程度、裂缝开展情况,及载荷-应变、载荷-挠度的变化.试验结果表明:在近似均布载荷作用下,采用碳纤维布加固预应力混凝土空心板,可以有效提高承载力:40%～120%左右,加固效果明显. |
| 关 键 词： | 碳纤维布 预应力混凝土空心板 受力性能 均布载荷 |

| Abstract: | The purpose of this paper is to focus on studying its flexural behavior under the uniformed load after the pre-stressed RC hollow slab is strengthened with CFRP.By the experimental method,eight actual-dimensioned hollow pre-stressed RC slabs are tested under the uniformed load in structural lab in order to analyze both flexural behavior and effects factored by bonding modes and strengthening quantities.The results show that its bearing capacity can be improved after the pre-stressed RC hollow slab is streng... |
