Over the years, SEESL has conducted research projects with university faculty and students, as well as working with groups such as NEES and MCEER. Below you will find current and past research projects that have been conducted here at SEESL.
This project aims to develop and validate bolted splice details for C-PSW/CF, a structural system designed for non-seismic regions like New York City and Boston. The focus is on areas where bolted splices are preferred over welded ones due to wind demands outweighing elastic seismic forces in splice design.
This project quantified the improvement in structural behavior of reinforced concrete shear walls retrofitted with a new method that allows the walls to rock over the foundation and self-center after an earthquake. The goal of the retrofit is to reduce seismic damage and allow rapid repair for resiliency.
The concept uses inexpensive braces called Buckling Restrained Braces (BRBs) and sliding bearings that work together to protect the bridge columns and superstructure from damage, so that the bridge can withstand the three-dimensional ground motions caused by earthquakes.
A real-time hybrid fire simulation algorithm is developed and tested to capture the expected behaviour of a steel column within a structural frame, considering the slow thermal expansion of the stiff steel column at early stages of fire, followed by a dynamic failure when it buckles.
An experimental program using a 6 degree-of-freedom earthquake simulator at the University at Buffalo was executed to generate data for supporting validation of numerical models for seismic fluid-structure interaction analyses of conventionally supported and base-isolated advanced reactor vessels.
Seismic design, qualification, and risk assessment of liquid-filled advanced nuclear reactors will rely on verified and validated numerical models for seismic fluid-structure interaction (FSI) analysis.
There is a growing interest in using coupled composite plate shear walls/ concrete-filled (CPSW/CF) for high-rise building construction, particularly to optimize the design for wind and/or seismic load combinations. This test series investigated the inelastic cyclic response of C-Shaped and T-Shaped walls typically used in core-wall structures.
SEESL is equipped with many large-scale, high-performance, dynamic and static actuators. These actuators provide the ability to conduct dynamic, pseudo-dynamic, and hybrid pseudo-dynamic testing. Find out more about our actuator capabilities.
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. Learn more about it.
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. Find out more about our shake tables.
The multi-fan wind tunnel is is controlled by 64 inertia array (8x8) of small axial fans. These fans can be controlled individually or in groups using the the supplied software. Each individual fan can reach a maximum of 5,500rpm (rotations per minute). Learn more about it.
