Abstract: A displacement‐control and uplift‐restraint device that can be installed within multilayer, elastomeric base‐isolation bearings is described. The device acts to limit the displacement of the bearings and is also able to ...

Abstract: This paper reports on the results from a comprehensive component testing program on a type of buckling-restrained brace known as the Unbonded Brace™. The experimental data are used to: (1) verify the results of theoretical ...

Abstract: Strong motion recordings from four seismically isolated buildings are used in time-invariant and time-variant modal identification analyses. The buildings are identified as equivalent, time-varying, linear dynamic systems ...
