Abutments supports at the end of an arch bridge that carry the load and keep the end and spreading out
Sprandrels vertical supports of an arch bridge used to distribute the weight of the roadway to the arch below
Anchorages securing devices that are embedded in the solid rock or massive concrete blocks that spread cables over a large area to evenly distribute the load and prevent the cables from breaking free.
Span the distance between two bridge supports
compression a force that acts to compress or shorten the thing it is acting on
tension a force that acts to expand or lengthen the thing it is acting on
buckling what happens when the force of compression overcomes an objects ability to handle compression
snapping what happens when tension overcomes an objects ability to handle tension
Dissipate to spread force over a greater area so that no one spot has to bear the brunt of the concentrated force
Transfer to move force from an area of weakness to an area of strenght
Truss supporting lattice work added to create very tall beams that add rigidity to an existing beam greatly increasing its ability to dissipate the compression and tension
torsion a rotational or twisting force
deck-stiffening trusses a supporting truss system beneath the bridge deck
resonance a fatal force to a bridge that is a vibration caused by a an extended force that is harmony with the natural vibration of the original thing. Resonance vibrations travel through a bridge in waves.
