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: Earthquake-induced damage often is caused by large deformation and floor acceleration. To ensure a fast function recovery process, controlling postevent permanent deformation also is very critical. Combining the merits of ...

Abstract: Superelastic shape memory alloys (SMAs) have inherent properties of complete recovery of large deformation and satisfactory energy dissipation under cyclic loadings. Such properties have attracted wide attention within the ...

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: 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 ...
