In the bridge sector, lateral bracings can be provided e.g. in the form of metal decks or horizontal truss bracings. Those bracings are more efficient at the regions of maximum lateral shear deformations generated from destabilizing forces of compression flanges e.g. near to the twisting ...
but they aren't based on the actual design of the deck. Though a good start to addressing something long overlooked, connections alone do not make up a complete lateral load design. Imagine a braced wall panel on a house with hold-down anchors but no bracing. This course gets well ...
Majority of the existing analytical methods of assessment of the stability of top chords of pony truss bridges rely on the stiffness ofU-frames that consist of cross-beams and truss bracing members. The available analytical methods of setting theU-frame stiffness seem to neglect the existence of...
