Abstract

An innovative mechanical device was developed and successfully used in this research program to apply low levels of prestressing force to glass fiber reinforced polymer (GFRP) bars. In addition, this device contains special features that allow for the application of GFRP bars to the retrofit of unreinforced masonry (URM) walls using the technique typically known as near surface mounted (NSM) reinforcement. Experimental studies were undertaken to investigate the feasibility of using this device for the retrofit of URM walls. A theoretical model was developed to calculate the shear capacity of URM walls retrofitted with prestressed NSM-GFRP bars. Numerical results matched well with the experimental results, which are described and presented in this paper.
