Experimental study on the flexural deflections of concrete
AbstractThis paper reports the results of an experimental investigation carried out to evaluate the bond stress behavior of basalt fiber-reinforced polymer (BFRP) bar and steel rebar (SR) in conventional C30-type concrete. The experimental program was conducted on testing 16 hinged beam specimens that were prepared according to BS 4449:2005+A2:2009 standard.

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 ...
