Why did the Galloping Gertie collapse?
Historically, the name “Tacoma Narrows Bridge” has applied to the original bridge nicknamed “Galloping Gertie”, which opened in July 1940, but collapsed because of aeroelastic flutter four months later, as well as the replacement of the original bridge which opened in 1950 and still stands today as the westbound lanes …
How long did Galloping Gertie last?
Slender, elegant and graceful, the Tacoma Narrows Bridge stretched like a steel ribbon across Puget Sound in 1940. The third longest suspension span in the world opened on July 1st.

What bridge collapsed in 1940?
The Tacoma Narrows Bridge
The Tacoma Narrows Bridge collapses due to high winds on November 7, 1940. The Tacoma Narrows Bridge was built in Washington during the 1930s and opened to traffic on July 1, 1940.
How do you stop the Tacoma bridge from collapsing?
Using CFD to simulate wind loads and FEA to investigate stresses and the structural behavior of bridges, engineers can prevent failures like the Tacoma Narrows Bridge collapse and build better and stronger bridges and buildings.
How many people died Galloping Gertie?
The Tacoma Narrows Bridge, nicknamed “Galloping Gertie,” fell into the sound during a windstorm on November 7, 1940. The bridge’s collapse was a lesson in poor design and engineering. Luckily, no was killed or seriously hurt in the incident. One dog did die.
What caused the Tacoma Narrows bridge to collapse?
The collapse of the Tacoma Narrows Bridge was driven by wind-generated vortices that reinforced the twisting motion of the bridge deck until it failed.
Can you swim Puget Sound?
While Puget Sound is cold and best for activities like paddle-boarding, kayaking, and fishing you can still find swimmable beaches near the city. From rock cliffs to sandy beaches, this park offers both saltwater in Puget Sound and freshwater at two of its inland lakes (Cranberry Lake and Pass Lake).
What causes aeroelastic flutter?
It is caused by a sudden impulse of load increasing. It is a random forced vibration. Generally it affects the tail unit of the aircraft structure due to air flow downstream of the wing.
The Tacoma Narrows Bridge, nicknamed “Galloping Gertie,” fell into Puget Sound during a windstorm in 1940. The bridge’s collapse was a lesson in poor design and engineering. The cause of the bridge failure was determined to be the solid girders, which took wind and acted like sails.
Where was the bridge Galloping Gertie located?
Located on State Route 16 between Tacoma and Gig Harbor, the bridge is 5,979 feet in length. That’s 40 feet longer than its predecessor, Galloping Gertie. Engineers designed the current bridge to carry 60,000 cars a day. But, now it handles an average of over 90,000 vehicles daily.
What bridge was called Galloping Gertie?
Answer Galloping Gertie was the nickname for the Tacoma Narrows Bridge that collaspsed during high winds in 1940.
