Abstract In order to study the parameters of automatic tying equipment for steel skeletons precast shear walls, 19 precast-shear-wall projects and 16,036 precast-shear walls have been explored, with thickness being studied according specifications sleeve diameters, difference between production without edge forms analyzed. The displays that should be able produce wall panels a height 2.5–2.95 m...

In this paper, we investigate the buckling of an air-water interface populated by lycopodium powder particles using a specially designed Langmuir trough with side walls that deformed affinely with the particle-laden interface in order to minimize the effect of shear during compression. Confinement effects from the side walls were studied by systematically reducing the width of the Langmuir trou...
