While members subject to compressive stress may also fail catastrophically, they typically do not fail from crack initiation. [2] Examples of bridge designs that would typically be considered fracture critical are: Most truss bridges with two main load-bearing assemblies; Two-beam girder bridges (three-beam bridges in California) Two-cell steel ...
3-Way Interchange Flyover Bridge, A part of River Bridge; Concrete and steel bridge Collapsed during construction, Design flaw in curvature section of a span resulted in collapse of a curved span slab during the removal of staging plates. 10 killed, 6 injured Total collapse of one wing. Bridge constructed after necessary modification in design ...
The critical load and strain gauge measurements at the load are noted and a graph is plotted. The crack tip opening can be calculated from the length of the crack and opening at the mouth of the notch. According to the material used, the fracture can be brittle or ductile which can be concluded from the graph.
Structural fracture mechanics is the field of structural engineering concerned with the study of load-carrying structures that includes one or several failed or damaged components.
CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present or scour may have removed substructure support. Unless the bridge is closely monitored, it may be necessary to close the bridge until corrective action is taken. 2
Designers typically adhere to standardised design codes when specifying tension members, which are critical components of structural systems. In the United States, the Steel Construction Manual published by the American Institute of Steel Construction (AISC) is the primary reference for structural steel design, while in Europe, the design is guided by the Eurocodes published by the Comité ...

Bridges usually require thick sheets of steel for their gusset plates, but trusses sometimes only require small sheets of aluminium for their gusset plate. The size and strength of the gusset plate depends on size and the function of the structure. The larger the force on the connecting members, the larger the size of the gusset plate.
