Seismic excitation can cause significant energy to be released within structures. By using
special devices, this energy can be consumed and dissipated without deforming structural …

This paper presents a practical multi-level performance-based optimisation method of
nonlinear viscous dampers (NVDs) for seismic retrofit of existing substandard steel frames. A …

In this study, a novel hysteretic damper is proposed for beam-column steel connections to
dissipate seismic energy. The proposed system is classified as a low-damage device and …

The application of shape memory alloy (SMA) in seismic-resistant devices has received
extensive attention due to its unique superelastic and shape memory effect. The poor energy …

The use of yield steel dampers in structures improves seismic resilience by efficiently
absorbing energy, reducing the impact of seismic forces, and enhancing overall safety and …

Considering that ordinary rubber materials have problems such as insufficient mechanical
properties and poor shock absorption effect, a right-angle viscoelastic damper (RVD) based …

A novel fabricated steel structure exterior beam-to-column connection with knee braces is
presented in this study, to improve the seismic performance and internal force distribution of …

Steel frames present significant storey drift during an earthquake because of insufficient
lateral stiffness. Thus, the objective of this study was to improve the lateral stiffness and …

Based on the application of a beam-column joint with replaceable energy-dissipating
elements and hinged beam-column proposed by the author, the seismic performance of a …

Welding stiffeners to angles improves the initial rotational stiffness and resistance of top-and-
seat angle connections, but the unintended side effect is lower ductility. To balance ductility …
