Abstract: Recent state‐of‐the‐art reports emphasize the generality of stochastic equivalent linearization techniques in the nonlinear dynamic analysis of stochastically excited structures. When a three‐dimensional frame is considered, ...

Abstract: This paper proposes novel self-centering (SC) seismic base isolators by utilizing shape memory alloy U-shaped dampers (SMA-UDs) with favorable superelastic behavior. Two different designs, which incorporate the SMA-UDs ...
