This
study presents the results of an experimental program conducted to determine
the strength of carbon fiber
reinforced polymers (CFRPs) bonded to low and
normal compressive strength concrete and masonry units that are finished with
or without plaster. In the experimental program, a total of 51
specimens with
different types of
anchorages (strip and embedded anchors) were tested. Test
results showed that ultimate strength of CFRPs bonded to plaster finished
specimens were significantly lower than those without plaster finish. It was
found that ultimate strength of surface bonded CFRPs with the use of embedment
at the free end and FRP dowels that act as shear connectors can result in
strength enhancements as high as three times of those without any special
anchorage. Based on slip measurements, a simple and effective strength model is
calibrated and proposed for strip type anchorages.
