Live Web Camera

Two live lab-sweep cameras are available on our telepresence site. Using these cameras, you can observe the activities on the test floor and the staging area in real time. Cameras include pan, zoom and tilt control.

Points of interest

1. Crosshead

Test specimens are bolted to the underside of the rigid steel crosshead and then to the strong floor. Actuators move the crosshead with six degrees-of-freedom to apply loads and deformations as determined by researchers. From tip to tip the crosshead is 29.3 feet.

2. Strong Wall

The strong wall is 7 feet thick and L-shaped. In tandem with the strong floor, its design permits a wide range of specimen configurations.

3. Strong Floor

The strong floor is 7 feet thick. A prefabricated steel grid was used to construct both the strong floor and the strong wall, allowing for precise placement of the holes used to tie down specimens.

4. Camera Tower

There are a total of four 24-foot configurable camera towers. Each tower houses a video camera, a still camera, a microphone and a lamp. Through the use of remotely controllable shelves, cameras can be positioned along the full height of the specimen.

5. Hydraulic Actuator

There are a total of 12 actuators (four each vertical, horizonal and ancillary) that move the crosshead with six degrees-of-freedom, transferring the forces and deformations to the test specimen.

6. Construction Staging

Test specimens are constructed and deconstructed in the staging area. The space is is 35 x 35 feet, located directly across from the test bay.
