Analysis on seismic performance of a new type of stiffening rib angle steel damper [PDF]
E3S Web of ConferencesThis paper proposes a stiffening angle steel damper for beam-column joints. The ABAQUS software is used to study the influence of the thickness, opening ratio and number of openings of the stiffening rib on the energy dissipation performance of the ...

Journal of Engineering and Sustainable Development, 2020 Researches concerning internal torsional strengthening of box beams are very little, since few researchers may study such method of strengthening. This research adopts employing of internal Framed Steel Stiffening Ribs (FSSRs) to strengthen reinforced ...

Vibrations of Rib-Stiffened Circular and Elliptical Plates [PDF]
The Journal of the Acoustical Society of America, 1968 This investigation deals with the determination of the fundamental frequency of vibration of simply supported and clamped rib-stiffened plates of elliptical boundary. It is assumed that the stiffeners are closely spaced and their height is moderate when compared with the thickness of the plate.

Azole γ‐Peptides Helix Switching via Heterocycle Substitutions
Angewandte Chemie, EarlyView.Heterocycle substitution in azole‐based γ‐amino acids enables control over the helical shape of heterocyclic γ‐peptides. S↔N permutation in thiazole residues switches a canonical 9‐helix into a flexible helix exhibiting discontinuous hydrogen bonding.
