| Abstract: | Based on the destruction characteristics of towns and villages housing,this paper uses basalt fiber fabric and flat steel strengthening methods to study the flexural strengthening of eight round wooden beams.According to the testing phenomenon,load deflection curve,plane-section hypothesis testing,ultimate load,and so on,the paper compares and analyzes the reinforcing effects of both strengthening methods,and proposes the applicable conditions of the selected strengthening methods for the villages houses. |
