Steel I beams or girders with sinusoidal corrugated profile webs have become popular in the recent development of steel structural designs, since corrugated-web (CWBs) can provide better performance terms less deformation and more stability against buckling failure. It is verified previous research that CWBs be considered as an alternative to replace normal designs their numerous favourable fea...

Abstract This work considers the method of corrugated sheet arrangement near column wall with aim to limit liquid fall on and increase concentration in near-wall area. Experiments were carried out at Koch 1Y packing sheets for various flow rates. report presents experimental results character edge effect middle shift from packing. The ribs this are directed downward Test was performed two posit...

The transverse compression and shear collapse mechanisms of a second order, hierarchical corrugated truss structure have been analyzed. The two competing collapse modes of a first order corrugated truss are elastic buckling or plastic yielding of the truss members. In second order trusses, elastic buckling and yielding of the larger and smaller struts, shear buckling of the larger struts, and w...

We propose a method for obtaining an improved representation of transients in audio signals. The representation is based on a damped sinusoidal model. To improve the representation, transient locations are modified in such a way that a transient can start only at the beginning of a sinusoidal segment. The introduced modifications facilitate a reduction of the number of damped sinusoids needed t...

In this contribution, the causes leading to undesired unevenness on exterior surface of a paper-based sandwich structure during manufacturing process are investigated. This provides insight into parameters that need be adjusted reduce waviness. A finite element model pressing is developed in commercial software ABAQUS and then used analyze formation unevenness. The adopted consists decorative l...
