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 ...
The inventory is developed for the purpose of having a unified database for bridges to ensure the safety of the traveling public, as required by the Federal Aid Highway Act of 1968. [1] It includes identification information, bridge types and specifications, operational conditions, bridge data including geometric data and functional description ...

[3] [4] [5] The design of tension members requires careful analysis of potential failure modes, specifically yielding (excessive deformation) and fracture, which are referred to as limit states. The governing limit state is the one that results in the lowest design strength, as it dictates the member's capacity and prevents structural failure.
Attempts have been made to increase the safety of bridges with pin and hanger assemblies by adding some form of redundancy to the assembly. Retrofits that add redundancy to pin and hanger assemblies include adding a "catcher's mitt"—a short steel beam attached to the bottom of the cantilevered girder that extends out beneath the suspended girder to "catch" the suspended girder should ...

Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
