Abstract: Due to the relatively low damping and sharp stiffness change, friction-based self-centering dampers are less effective in controlling peak interstory drift (PID) and peak floor acceleration (PFA). To address these concerns, ...

Abstract: Shape-memory alloy (SMA) knee-braced frames (KBFs) are a type of seismically resilient frame buildings. Knee braces (KBs) in this system are the SMA buckling-restrained braces, which provide both self-centering and ...

Abstract: In seismic prone regions, many old bridges deserve retrofitting measures to improve their seismic resilience. The recently proposed buckling-restrained shape memory alloy (SMA) dampers, which can maintain axial resistance ...
