The collapse of Baltimore bridge in the US is from the technical point of view is a testament of dynamic effect of impact forces and loads applied upon the bridge piers by passing ship or barge. It is interesting that such force was neglected in the design of a river bridge where ships and barges are often passing through and could collide with it as it already has happened. The cost may be a reason, however, safety of people’s lives comes first. A simple blocking perimeter around the bridge piers well designed can do the job with a reasonable cost. Whatever the cause was (mechanical failure or human error) it was enough to cause such tragedy and loss of life and money spent in that project that its workers thrived hard to save. In the end, this is life: full of lessons.

March 26, 2024 - Bridge Collapse in Baltimore: A Brief Overview! A recent maritime accident led to the collapse of Baltimore’s Francis Scott Key Bridge when the cargo ship Dali collided with it. The impact was significant enough to destroy a concrete pier, causing the structure to fail. The bridge, dating back to 1977, faced an extraordinary event beyond its anticipated challenges.

In a distressing incident yesterday, a cargo ship collided with one of the pillars of the Baltimore bridge causing significant structural failure that led to collapse of the bridge. Wondering if the bridge was structurally optimized at the design stage for such collision and load scenarios. #StructuralEngineering, #OptimalDesign #EfficientStructures #StructuralSolutions #InnovativeDesigns #OptimizedPerformance #StructuralDesignTrends #BridgeCollapseAlert #engineeringfailure ##StructuralOptimization

On March 15, 2018, a newly installed pedestrian bridge at Florida International University tragically collapsed, resulting in six fatalities and ten injuries. This failure is another terrible reminder of the role played by the evitable human factors in facilitating structural failures.

How can the choice between strip and raft foundations significantly impact the stability and longevity of buildings in subsidence-prone areas?

Failure of overhead structures always means that life is at stake..it is always a serious matter for structural engineers to ensure integrity and that structure is soundly built..#bridgeengineering #civilengineering #structuralengineering

By now we've all heard about the tragic collapse of the Baltimore bridge. To help avoid future incidents like the one what about a proactive ... #protective installations like these 'dolphins' ? "A dolphin is a protective object that may have its own fender system and that is usually circular in plan and structurally independent from the bridge. Their main function is to protect adjacent structures from the impact of a vessel." Infrastructure resilience can be significantly enhanced by adopting such protective installations.

Baltimore Bridge Collapse (Ship Impact Load Design) The Francis Scott Key Bridge in Baltimore collapsed after a cargo ship hit the bridge abutment. The resulting design ship for the Suspension Bridges, based on analysis of passing ship-tanker traffic and considering the largest ships likely to pass in the future: Ship crash frequency value (AASHTO): 10-4 (annual crash frequency is 0.01 in 100 years) Ship speed: 10 knots (1 knot = 1.852 km/h) Based on all these, the design impact (nose) load = 372 MN. (1 MN = 100 tons). Different preventive measures can be taken for each suspension bridge, depending on its traffic projection and geological and meteorological conditions.
