Bond-slip and cracking behaviour of glass fibre reinforced polymer reinforced concrete tensile members
In this work, a methodology has been developed to implement the bond behaviour between concrete and GFRP bars in the numerical modelling. Based on experimental results and applying the inverse method, the bond law to be used in the numerical model is obtained. The thesis continues with two experimen...

| Resumo: | In this work, a methodology has been developed to implement the bond behaviour between concrete and GFRP bars in the numerical modelling. Based on experimental results and applying the inverse method, the bond law to be used in the numerical model is obtained. The thesis continues with two experimental campaigns on GFRP RC elements under tensile sustained loads. The first experimental campaign consisted in testing GFRP RC elements with different target concrete strengths. The tests were carried out for a period between 35 a 39 days. Experimental results were compared with analytical codes for steel RC structures. The second experimental campaign consists on the analysis of bond of such structures under sustained load. The specimens were tested for a period between 90 and 130 days. Slip stabilization was observed to occur at 60 days after the beginning of the tests. |
