Grand Canyon Skywalk is a transparent bridge horseshoe-shaped console, is a very important tourist attraction in Arizona near the Colorado River, Grand Canyon Skywalk is made on the side of a canyon in the Grand Canyon.
(4,770 ft (1,450 m) and the elevation of the Colorado River in the base of the canyon as 1,160 ft (350 m), the height of the precisely vertical drop directly under the skywalk is between 500 ft (150 m) and 800 ft (240 m))
As resistant construction, has some very interesting specifications:
The Skywalk deck was designed for a 100-pound-per-square-foot live load along with code required seismic and wind forces.
It can support the equivalent of 71 loaded Boeing 747 aircraft or an 8.0 magnitude earthquake within 50 miles (80 km)
Fine-tuning of the project occurred after a wind loading and pedestrian induced vibration analysis.
The walkway could carry 822 people that weigh 200 pounds (91 kg) each without overstress, but maximum occupancy at one time is 120 people.
Fine-tuning of the project occurred after a wind loading and pedestrian induced vibration analysis. Two tuned mass dampers were installed inside the outer box beam as well as one inside the inner box beam at the furthest extension of the Skywalk to reduce pedestrian footfall vibration.
