Abstract: Effective stability bracing of beams can be achieved by either preventing lateral movement of the compression flange or restraining twist of the beam cross section. Bracing that restrains twist is aptly referred to as ...

Abstract: Guidance for the lateral-torsional buckling behavior of singly-symmetric, nonprismatic (stepped flanges) sections are often absent from design specifications or are overly simplified. This paper presents simplified design ...

Abstract: Rigid origami is seen as a fundamental model in many self-folding machines. A key issue in designing origami is the rigid/nonrigid foldability. The kinematic and foldability of Kresling origami, which is based on an origami ...
