Experimental Study On Rehabilitation Of Corroded Pipes, Sachith Jayasuriya
Electronic Theses and Dissertations
Corrosion is a severe problem that affects oil and gas pipelines all over the world. When combined with the complex loading combinations faced by buried pipelines, the effects of corrosion can be devastating. Corrosion decreases the burst pressure, longitudinal load-capacity, and lateral load-capacity of affected pipes. Much research has been conducted to address this problem, and many repair techniques have been developed, including the use of fibre-reinforced polymers (FRPs). Most of the research that has been conducted on the use of FRP composites to repair pipes is concerned with increasing the burst pressure. The purpose of this study is to …

Reinforcing And Rehabilitative Performance Of Basalt Fibre Reinforced Polymers For Concrete Beams, Jason Philip Duic
Electronic Theses and Dissertations
This thesis presents the experimental results of laboratory testing conducted on full-scale concrete beams that are reinforced and rehabilitated with basalt fibre reinforced polymer (BFRP) products. The first study compares the structural behaviour of BFRP and steel reinforced beams. It was found that current design standards were able to predict the shear capacity of BFRP reinforced beams with varying accuracy. However, it was found that BFRP stirrups without proper bends did not prevent shear failure. Thus, proper BFRP stirrups need to be developed. The second study was on flexural strengthening and rehabilitation of concrete beams with BFRP composite. It was …
