Abstract

Abstract

An experimental and theoretical study was conducted on the bending and composite properties of five full-size prefabricated concrete sandwich panels with new steel-glass FRP composite connectors （SGCCs）. The experimental results showed that the bending bearing capacity of sandwich panels was not proportional to the total number of SGCCs， mainly depending on the arrangements of the SGCCs. The number and spacing of SGCCs arranged along the short edge of the panel had a significant impact on the bending bearing capacity and composite properties of the sandwich panel. Before the yield of the sandwich panel， the changes in the number of SGCCs at the end of the panel relative to the middle and 1/4 of the panel had a more significant impact on the bending bearing capacity and composite properties of the sandwich panel. Sandwich panels exhibited partially composite properties. The degree of composite action was positively correlated with the flexural bearing capacity. The experimental results were in good agreement with the theoretical calculation results.
