The University at Buffalo's (UB) Structural Engineering and Earthquake Simulation Laboratory (SEESL) provides services to the faculty and staff of the Department of Civil, Structural, and, Environmental Engineering (CSEE), as well as seismic qualification and other testing services for industry clients. SEESL is equipped with a diverse array of test equipment and platforms, including earthquake simulation tables, a geotechnical laminar box, a strong floor and strong wall, and more.
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.
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.
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.
