Facilities

Structural Vibration and Shock Laboratory

Description: The Structures Research Laboratory, located in Castleman Hall Room 115, is a 60' by 35' strong floor serviced by a 25 ton overhead crane. Equipment in the laboratory includes:
    • 6DOF shake table with a 4'x4' slip table a 4" peak to peak dynamic stroke and capable of a 2g peak acceleration (horizontal) with a 1 ton payload.
    • uniaxle shake table with a 5'x5' slip table a 6" peak to peak dynamic stroke and capable of a 2g peak acceleration with a 1 ton payload.
    • Under Construction: A second 6DOF shake table with a 4'x4' slip table a 4" peak to peak dynamic stroke and capable of a 2g peak acceleration (horizontal) with a 1 ton payload.
    • Under Construction: Broad-bandwidth shake (target bandwidth of 0.1-100 Hz)
    • Under Construction: Shock table
    • 2 kip hydraulic actuators
    • real-time hybrid testing capabilities with: dSpace, Speadgoat and xPC real-time controllers
    • 36 channel DataPhysics Data Acquisition unit
    • fully monitored scaled highway bridge model
    • operational traffic light signal structure with mass damper system
    • MTS hydraulic pump (30 gpm)
    • MTS servo-controller
    • MTS hydraulic service manifold
    • Two Satec Hydraulic Universal Testing Systems

Bench-Scale Structures Laboratory

Description: The bench-scale structures laboratory, located in CAST 209, consists of a 5x5 ft bench-scale strong floor and reaction wall, multiple 100 lbf linear actuators, a bench-scale seismic simulator, and associated sensors.

    • The bench-scale seismic simulator equipment consists of a Shaker II (STII) system from Quanser. The STII has a 46x46 cm slip-table driven by a ball-screw mechanism with an operating frequency of 0-20 Hz, a +/-7.6 cm stroke and a peak acceleration +/-1 g with an 11.3 kg payload. The STII interfaces with a PC through the Quanser Q8 board and is controlled using WinCon real-time software.
    • PCB has donated various sensors to help establish a laboratory to teach structural dynamics, including: accelerometers, force sensors and strain gauges.
Bridge Monitoring Equipment

Description: In addition to the equipment on the permanently monitored highway bridges in Connecticut, the laboratory has a BDI wireless strain monitoring system used for bridge monitoring efforts.

    • The permanent monitoring systems utilize National Instruments CompactDAQ hardware and accelerometer, strain, temperature, microphone and camera sensors.
    • The portable monitoring system is a BDI STS4 Wireless Structural Testing System with 5g accelerometers, strain sensors, and string poteniometers.
