The following principles are proved : increasing cfp adhesive length will release the concentrating of shear stress near the cutoff point, this will lead to the increment of loading - bear capacity of concrete beams ; increasing the thickness of cfp will improve the transition of load from concrete beam to cfp, this is useful to exert the potential of cfp ; in creasing the anti - shear modulus of adhesive will result enhance the concentrating of shear stress, this is harmful to the effect of cfp reinforced concrete beams
本文的理論分析結果可以表明：增加碳纖維板的粘結長度可以緩解碳纖維板端部界面上的剪應力集中，改善混凝土梁結構的加固效果；增大碳纖維板的粘結厚度可以增大界面上的剪應力，改善混凝土樑上載荷向碳纖維板的傳遞效果，有利於充分發揮碳纖維布的潛能；如果粘結膠層的抗剪模量過大會加劇剪應力的集中，從而對碳纖維加固的效果不利。 -
The experiment highlights the effect of cfp length and the adhesive mode of cfp on the loading - bear capacity of cfp reinforced beams. from the results, it is obvious that when the cfp adhesive length increases, the loading - bear capacity increase too. when the cfp length is 10mm, the loading - bear capacity is 1. 81 - 2. 27 times as much as the value of non - reinforced beam ; and when the cfp length increase to 200mm and 350mm, the loading - bear capacity increase to 3. 35 - 3. 97 times and 3. 61 - 5. 76 times as much as the value of non - reinforced beam
從試驗的結果來看，碳纖維的粘結長度增加對混凝土梁的加固效果的影響十分明顯：當碳纖維粘結長度為100mm時，混凝土加固梁的極限承載力一般為未加固混凝土梁的1 . 81 - 2 . 27倍；而當碳纖維粘結長度為200mm和300mm時，混凝土加固梁的極限承載力則分別為未加固梁的3 . 35 - 3 . 97倍和3 . 61 - 5 . 76倍。 -
Thereinto, where the shoe pinches is how to choose character related to adhesive capacity from acoustic signal, and it is primary content in this paper, too
其中，如何從聲激勵聲信號中獲取與粘接性能有關的特徵是該方法的關鍵所在，也是本論文的主要內容。 -
Acoustic excitation signal is processed with wavelet analysis in this paper, and chooses characters related to adhesive capacity from acoustic signal in the time domain and frequency domain. these characters is the input of nerve network which is used to non - mangle test about mechanics capacity of adhesive structure, and establish the base for classify distinguishing effectively and forecast
本文採用小波變換的方法對採集到的聲激勵信號進行分析，在時-頻域提取出與粘接性能有關的特徵量，用於粘接結構力學性能無損檢測的神經網路輸入，從而為有效進行分類判別和預報奠定了基礎。 -
By contrast, the effect of improving the adhesive mode of cfp, that is to say, epoxy - bonding double carbon - fiber composite plates or epoxy - bonding u shape cfp anchorage is less notable. the loading - bear capacity of double cfp reinforced concrete beams is 8. 5 - 11. 3 percent higher than that of the single cfp reinforced concrete beams ; the loading - bear capacity of epoxy - boding u shape cfp anchorage reinforced beams is 4. 7 - 18 percent higher than that of the single cfp reinforced beams
相比之下，改善碳纖維板的粘結方式，即採用粘結雙層碳纖維布和在單層碳纖維布的基礎上粘結u形包頭的影響要小一些：採用雙層碳纖維布加固比單層碳纖維布加固時的極限承載力提高了8 . 5 % - 11 . 3 % ；採用包頭形式加固比單層碳纖維布加固的極限承載力提高了4 . 7 % - 18 % 。
