An example of a Fink truss bridge. It is identified by the presence of multiple diagonal members projecting down from the top of the end posts at a variety of angles. These diagonal members extend to the bottom of each of the vertical members of the truss with the longest diagonal extending to the center vertical member. [4]
The bridge's paired end posts at mid-span showing connection of diagonal tension members with anchor casting. The bridge was built for an unknown location on the main line of the Baltimore and Ohio Railroad in 1852 and was moved to its present location, spanning the Little Patuxent River on the spur to the Savage Mill, in 1887. This spur line ...
A structural drawing, a type of engineering drawing, is a plan or set of plans and details for how a building or other structure will be built. Structural drawings are generally prepared by registered professional engineers, and based on information provided by architectural drawings. The structural drawings are primarily concerned with the ...
A steel detailer is a person who produces detailed drawings for steel fabricators and steel erectors. The detailer prepares detailed plans, drawings and other documents for the manufacture and erection of steel members (columns, beams, braces, trusses, stairs, handrails, joists, metal decking, etc.) used in the construction of buildings, bridges, industrial plans, and nonbuilding structures.
A KT gusset plate connects several members together through one gusset plate. The gusset plate is welded to a beam, and then two or three columns, beams, or truss chord are connected to the other side of the gusset plate through bolts or rivets or welds. [3] A uniform force bracing connection connects a beam, column, and one other member.
In some cases, the plate girders may be formed in a Z-shape rather than I-shape. The first tubular wrought iron plate girder bridge was built in 1846-47 by James Millholland for the Baltimore and Ohio Railroad. [2] Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders ...
An arbitration board has ruled that U.S. Steel may proceed with its proposed acquisition by Nippon Steel, a deal that faces strong opposition from its workforce. The board, which was jointly ...
A simple lattice truss will transform the applied loads into a thrust, as the bridge will tend to change length under load. This is resisted by pinning the lattice members to the top and bottom chords, which are more substantial than the lattice members, but which may also be fabricated from relatively small elements rather than large beams.
