The Cowboys Stadium near Dallas, Texas, at the time of its construction, set several records as the world’s largest single span structure, and as the world’s largest dome stadium, with 1/4 mile long Arch trusses supporting the world’s largest retractable roof.
To handle the more than 9,000 ton thrust reaction at each abutment supporting the largest domed stadium arches in the world, Bencor installed four 176 feet long by 71 feet deep by 18 feet wide slurry wall abutment boxes at each corner of the stadium.
The slurry walls were installed using state-of-the-art Leffer clamshells in order to penetrate the very hard, sandstone layers.
The steel cages in this box structure were heavily reinforced with more than 62 pounds per square foot of steel and the U-panel at each end of the boxes were constructed monolithically. These cages weighed in excess of 90 tons.
