Cantilever bridges are constructed using pairs of cantilevers, where each cantilever supports one end of a central section. A cantilever is a beam supported at only one end, carrying loads through moment and shear stress to the supported end. Most truss bridges have upper chords in compression and lower chords in tension, but cantilever truss bridges invert this design by placing the beam on the bottom and providing support on the top.

1. CANTILEVER BRIDGES

2. A cantilever is a beam supported on only one end.

3. The beam carries the load to the support where it is resisted By moment and shear stress.

4. Cantilever construction allows for overhanging Structures without external bracing.

5. In cantilever bridges the cantilevers Are usually built in pairs With each cantilever used To support one end of a Central section.

6. Most trusses have the upper chord under compression. And the lower chord under tension

7. In a cantilever truss the beam is on the bottom And all the support is on the top. These are all truss Bridges.
