Experimental study on seismic performance of frame flat columns with high axial compression ratio [PDF]
E3S Web of Conferences, 2020 When the lateral stiffness of the frame flat column is relatively small, the strength of the frame flat column is not enough to resist the large horizontal earthquake force and seriously deformed, which leads to the structure fail and could not work normally.

NiTiCu Transverse to Axial Strain Ratio Analysis During Tension/Compression Tests
Materials Today: Proceedings, 2015 © 2015 The Authors. Tension-compression asymmetry in polycrystalline NiTiCu tubes was studied during elastic and transformation zone using strain gauges rosettes. Axial and transverse strain measurements from strain gauges were used to calculate a localized strain ratio through tensile and compression tests at different temperatures.

Study on axial compression property of thin walled tube filled with negative Poisson’s ratio lattice
Advances in Mechanical Engineering, 2023 In this paper, a new type of thin-walled energy absorbing structure filled with auxetic lattice structure has been proposed. The deformation mode and mechanical responses of the new filled tube under compression load have been studied through quasi-static compression experiment and numerical simulation.
