Sekundarni naslov: | Strengthening of a reinforced concrete girder with a CFRP laminate under bending load |
Sekundarni povzetek: | The master's thesis deals with strengthening of a girder made of reinforced concrete with a CFRP laminate under bending load. It includes several different analysis and dimensioning of a nonstrengthened and strengthened reinforced concrete girder with a CFRP laminate. The use of non-destructive and destructive methods conveys the dimensions, position of rebars and material characteristics of the existent reinforced concrete girder. The determination of those is crucial for the accuracy and successfulness of all further analysis and dimensioning of the strengthening CFRP laminate. The thesis includes a four point bending test of both non-strengthened and strengthened reinforced concrete girder. After the experiment several analysis were conducted, a numerical analysis using the Abaqus software, an analytical calculation in accordance to the Eurocode standard and finally a comparison of the two. The comparison of the results of the analytical calculation and the numerical analysis with the results of the experiment yielded the accuracy of the determined behaviour for the nonstrengthened and strengthened girder with the help of analytical and numerical methods. The last part consists of assessment of the load-bearing capacity of the strengthened reinforced concrete girder with a CFRP laminate in accordance to corresponding standards and recommendations. The results of the projects %Design% state for the strengthened girder are compared to the results of the beforehand made analysis of the actual state which shows the necessary safety for dimensioning. A simple software for optimal dimensioning of a bending loaded reinforced concrete girder with a CFRP laminate was developed based on the equations for dimensioning and calculus based safety controls in correspondence with recommendations. |
