Abstract

In order to improve the interfacial comprehensive performance of composite wallboard, an experimental study on the interfacial mechanical properties of sandwich exterior wallboard with FRP composite pipes as connectors was carried out. The influence of the number and layout of FRP composite pipe connectors on the shear resistance of the interface was investigated through the experiment of FRP composite pipe reinforced interface extrusion. The ultimate strength, displacement and failure mode of the connectors were determined. The deformation of the connectors and the sliding ability of the interface, the shear distribution of the interface and the shear bonding degree of the interface were investigated. Four interface shear specimens were designed. The characteristics of interface stress stage and ultimate failure mode were investigated. Based on the experimental study, the influence of the layout parameters of the innovative connector on the mechanical properties of the interface is proposed, and the design suggestions to ensure the spatial effect of the interface are put forward. The research work provides a scientific basis for the design of FRP composite pipe connectors.
