Mechanical characteristics of steel truss bridge

(1) The beam pier column is rigidly connected, and the beam is unloaded due to the bending resistance of the pier column. The entire system is a compression-bending structure and also a thrust structure.

(2) The clearance under the steel truss bridge is larger than that of the arch bridge, and a smaller span can be built under the same clearance requirements.

(3) The construction of steel truss bridges is more complicated, and is generally used for overpasses and overpasses in cities or highways with small spans.

(4) Steel truss bridges using prestressed concrete and cantilever construction have become one of the competition options for long-span bridges.
