Map of SEESL

Layout of SEESL

SEESL includes four large spaces as shown in the adjacent plan view. The original laboratory space was completed in 1983 and is located at the south end of the facility. The newer, larger laboratory space was completed in 2004 and is at the north end. The other two spaces are used for storage, receiving and fabrication and are located between the two main laboratory spaces.

Apart from SEESL, Ketter Hall also houses many of the Civil and Structural Engineering faculty offices and a number of smaller laboratories used for structural and geotechnical engineering for research and instruction.

For earthquake simulations, one of the services we provide are shake tables. Currently, there are two, relocatable 7.0m x 7.0m platforms with six-degrees of freedom. Each table is capable of 50 tons payload.

The Geotechnical Laminar Box is designed for soil-foundation-structure interaction studies at or near full scale. The laminar box and the soil contained within deform in a manner that simulates free ground response under simulated seismic excitations. The laminar box can be assembled to a maximum height of six meters.

SEESL is equipped with two strong floors, located in Testing Area 1 and 2. Area 2 includes Strong Reaction Walls on the far east of the testing area. Click the image to the right for a map of the strong floor in Testing Area 2.

SEESL is equipped with two reaction walls ("strong walls") on the east end of the new laboratory. The first is located adjacent to the strong floor, and the other is adjacent to the shake table trench. See below for dimensions and capacities of both strong walls.

The pump room, located in the basement of the Ketter Hall SEESL lab addition, houses four MTS 506.92 Hydraulic Power Supply (HPS) units, each rated at 185gpm (700lpm) flow with 3,000psi (207 bar) working pressure. Each HPS consists of two high-pressure, variable volume main pumps and a low pressure “supercharge” pump that draws oil from the reservoir and supplies a constant oil pressure and flow to the inlets of the main pumps.

The SEESL lab is equipped with multiple large-scale, high-performance, dynamic and static actuators. These actuators provide the ability to conduct dynamic, pseudo-dynamic, and hybrid pseudo-dynamic testing, in which large structures could be directly subjected to dynamic excitations without the need for shake tables. Two large reaction walls are located on the eastern side of the lab, one of which is directly next to our shake tables. If equipped with dynamic actuators, this will allow for the application of computer-predicted external forces on shake table-mounted substructures, thus simulating the reaction of the entire structure (Real-Time Dynamic Hybrid Testing, or RTDHT).

The laboratory is equipped with a variety of instrumentation options, which include motion and loading sensors, as well as strain gauges. All distance and loading sensors are calibrated and documented annually.
