Experimental study on the shear resistance of steel-wood composite member based on glue and bolt connection

Abstract

This study investigates the shear connection performance of steel-wood composite members, using both experimental research and numerical analysis. The experimental investigation explores the impact of glue length and thickness on the performance of the glue connection, while also examining the effects of bolt spacing, bolt number, and bolt diameter on the performance of the bolt connection. Furthermore, a comparative analysis is conducted to assess the performance differences among different types of connections, namely glue connection, bolt connection, and composite connection. Subsequently, a numerical analysis model is developed and validated by comparing it with the experimental results. The numerical analysis verifies the shear transfer mechanism of interfaces with various connection modes. Building upon the understanding of the shear transfer mechanism, an equation is derived to calculate the shear bearing capacity of the interface. The validity of this equation is demonstrated through the test results. The findings presented in this paper establish a robust theoretical foundation for future research, development, and engineering applications related to steel-wood composite members.
