18 specimens of cold-formed steel three limbs built-up section members are tested under axial compression load in this paper. The section forms are divided into two categories: A and B. Load-displacement (P-Δ) curves and failure characteristics of specimens are obtained. The results show that: As to section A members, the failure characteristics of LC, MC and SC series of specimens are flexural-torsional buckling, torsional buckling and distortional buckling, local buckling and distortional buckling. As to section B members, the failure characteristics of LC, MC series of specimens are flexural buckling, while local buckling and distortional buckling for members of SC series.

To acquire the fatigue characteristics of viscoelastic suspensions mounted in newly-developed construction vehicles, an experimental study of fatigue characteristics should be carried out on the vibration damping rubber suspension components. However, due to the lack of corresponding fatigue failure criteria for the damping rubber components, how to determine the parameters for the accelerated fatigue experiments becomes a new research subject. Based on the accelerated fatigue experiments on the viscoelastic suspensions, the parameters on fatigue failure characteristics such as the cycle index (ne), the slope (k) of S–N logarithm curve and the allowable temperature rise, and so on, were investigated. To develop a new viscoelastic suspension for the crawler bulldozer, three types of rubber made from different formulas for the viscoelastic suspensions were studied and their experimental loads were divided into 8 levels in terms of the practical working conditions of the bulldozer. The accelerated fatigue experiments of viscoelastic suspensions were performed and the obtained parameters were applied to the fatigue experiments for the suspensions of a newly-designed 386 kW crawler bulldozer. Under the industrial application over 4,000 hours, the results were shown to be consistent with the predicted experimental values.

Based on the flexural-shear and press-flexural-shear test of four scale HSW model building with High Shear-Span Ratio, The seismic behavior of the slit and integral HSW are discussed, then the failure characteristics and capacity of HSW under Vertical load and seams are analyzed. The result of experimental study proves that the ductility and the property of energy dissipation of HSW are well; Vertical load could increase the capacity and deformation, decrease the energy dissipation of HSW. And the seams of wall could improve the ductility and the property of energy dissipation of HSW , lower the capacity.

This article presents an experimental study on hollow floor slab-column-reinforced connections, which are enhanced by installing locally solid zone of slab around the column and hidden beam in the floor. To investigate the punching-shear behavior of hollow floor slab-column-reinforced connections, six hollow floor slab-column-reinforced connections under vertical load were conducted on three types of connections with different thickness, namely, two hollow floor slab-column-reinforced connections without punching component, two hollow floor slab-column-reinforced connections with bent-up steel bars, and two hollow floor slab-column-reinforced connections with welding section steel cross bridging. Meanwhile, the strength, stiffness, failure mode, and ductility of hollow floor slab-column-reinforced connections with punching components were obtained and compared with the hollow floor slab-column-reinforced connections without punching component. The results showed that hollow floor slab-column-reinforced connections had the double failure characteristics including punching shear and flexural failure, and flexural failure was the main failure mode as a result of installing hidden beam. The hollow floor slab-column-reinforced connections with punching components exhibited higher initial stiffness and higher loading capacity than hollow floor slab-column-reinforced connections without punching components, but welding section steel cross bridging have a better on improving the connections’ punching-shear capacity than bent-up steel bars.
