Abstract: “This paper describes the mechanical properties of truss girders with Z-shaped clips through experiment. The result shows that the failure mode of truss girder is categorized as lateral buckling-induced destabilization. By comparing the mechanical performance and the economy indices between truss girder with butterfly-shaped clips and truss girder with Z-shaped clips, the feasibility of truss girder with Z-shaped clips is demonstrated.”
