this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...

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...

A pragmatic design strategy to achieve unusual mechanical responses in metal lattice structures is deployed. This strategy, referred as behavior by design, illustrated with an architectured material fabricated provide a “whistle-blower” response under tensile loading. Struts geometries, e.g. dog-bone struts and corrugated struts, are assembled parallel standard unit-cell obtain the targeted ela...
