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.
Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Hydrodynamic scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure. [1] In the United States, bridge scour is one of the three main causes of bridge failure (the
A local councillor, who went to the bridge to record the extant structural issues, captured the beginning of the collapse. [198] Portland & Western Mary's River Rail bridge Corvallis, Oregon United States: 4 January 2025 Rail bridge No deaths or injuires reported Bridge collapsed as train was crossing, one car fell into Mary's River.

The Penang Second Bridge in Penang, Malaysia has completed the implementation and it's monitoring the bridge element with 3,000 sensors. For the safety of bridge users and as protection of such an investment, the firm responsible for the bridge wanted a structural health monitoring system.
Single box girder bridge , flyover above eastern approach of the San Francisco–Oakland Bay Bridge. A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete.
NBI is a template that simplifies and better organizes reference calls to the Federal Highway Administration's (FHWA) National Bridge Inventory (NBI), an annually published data set on all bridges at least 20 feet (6.1 m) in length in the United States. This data includes the coordinates of the bridge, bridge type, when the bridge was built and ...
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. [1] [2]: 85 [3] The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons ...
Girder bridges have existed for millennia in a variety of forms depending on resources available. The oldest types of bridges are the beam, arch and swing bridges, and they are still built today. These types of bridges have been built by human beings since ancient times, with the initial design being much simpler than what we utilize today.
