Abstract: In order to investigate the mechanical behavior of GFRP (glass fiber reinforced polymer)-concrete composite slabs, three continuous GFRP-concrete composite slabs were tested under the static loads. The three composite slabs were connected with steel girder supports by either epoxy resin or shear studs. The experimental results show that all specimens are damaged with local punching shear failure at the loading pads. The load redistribution is not observed in middle and end supports. The composite slabs exhibit good mechanical performance and deformation compatibility. Then, based on the plastic limit theory, a calculation method for the ultimate load capacity of the GFRP-concrete composite slab was proposed. By comparing the test results with the predicted values, the effectiveness of the proposed method on predicting the ultimate load capacity of GFRP-concrete composite slabs is verified.
