Abstract:
In order to disclose the destruction mechanism of sheetconcrete interface of concrete structure strengthened by sheets, the tests with 12 pairs of sheet bonded on concrete structures were performed to study the influence of some factors such as concrete strength, treatment craft, layer number and sheet type on the bonding effects, and the bonded mechanism and destruction shape were analyzed to find the inherent laws for bonding mechanism of sheetconcrete interface. The results show that the influence of concrete surface treatment craft on the bonding effects cannot be ignored; the bonding strength presents a nonlinear increment with the increase of sheet layer numbers; there is a decrease for the utilization ratio of bonding strength with the increase of sheet layer numbers; the bonding effects of steel plates are worse than the ones of sheets. 3 tabs, 9 figs, 11 refs.
