摘要：The bond between glass fiber reinforced plastic (GFRP)/steel wire composite rebars and concrete is the key problem to the performance of concrete structures reinforced with GFRP/steel wire composite rebars. In this study, pull-out test was tested to experimentally investigate the bond strength of GFRP/steel wire composite rebars to concrete. The test variables were the nominal diameter, the embedded length, the concrete compressive strength, the concrete cover thickness and the concrete cast depth. Based on the two modification factors of 1.2 and 1.6 to account for the top rebar effect and concrete cover effect, respectively, a new formula is proposed for the calculation of development length for GFRP/steel wire composite rebars.
