钢板粘贴碳纤维加固研究

On intensifying research of steel slab sticking carbon fiber

通过6块钢板(其中1块对比板和5块加固板)进行了集中力荷载下的试验,比较了在不同加固方法下屈服荷载、极限荷载的提高程度和变形的减小程度及其影响因素,试验表明用碳纤维布和碳纤维板加固钢板可以有效提高钢板的屈服荷载和极限荷载,并增加钢板的刚度。

According to the experiments for six steel plates （including one comparing slab and five stiffening slabs） under the concentrated force toad, the paper compares the improvement degrees for the yield load, the ultimate load and the decreasing degree for the deformation, as well as influential factors. The experiments show the intensified steel slab with carbon fiber can effectively improve the yield load and ultimate load and improve the stiffness of the steel slab.
