The Structural Testing Laboratory

structural_testing_lab.jpgThe Advanced Structures and Composites Center’s Structural Testing Laboratory, constructed in 2000,  is an 80'-x-110'-x-30'-high facility designed to evaluate structures such as bridges, buildings, transmission structures, airplane wings, ship hulls, large propeller and windmill blades, connections, beams, girders. The facility design allows full-size tractor-trailers carrying test specimens to drive easily into and out of the lab. The test frames are supported by three hydraulic pumps designed to operate at 3000 psi.

 

 
Reaction Floor

Reaction Floor - 90' long x 45' wide x 14' deep,  reinforced concrete, stainless-steel hardline hydraulic piping with 4,600-psi rating, multiple load points, over 600 reaction points on a 2' grid, individual anchor-point capacity of 386,000 lbs. Open box-girder reaction-floor construction allows actuator loading from either above or beneath the floor.
