Investigation on the mechanical behavior of glulam spliced joints connected with self-tapping screws and prestressed steel strips
Highlights Glulam spliced joint connected by steel strips and self-tapping screws was proposed. The feasibility of the three-dimensional finite element model was verified. Theoretical analysis was provided to estimate the stiffness and ultimate moment.
Abstract A glulam spliced joint connected with self-tapping screws and prestressed steel strips was proposed and investigated. An experimental study was conducted considering the variation in the arrangement of the self-tapping screws and steel strips. The specimen with an inclination of 60° screws exhibited the highest ultimate load, whereas the specimen with screws in the X-position with the inclination of 60° had the highest ductility. Finite element analysis was performed and verified to be effective in simulating the mechanical behavior of the proposed joint. Moreover, the proposed theoretical model exhibited a high accuracy when predicting the bearing capacity and stiffness.
