Rotational friction dampers (RFDs) have been proposed as one of the passive control
devices in order to enhance the seismic performance of inelastic structures and dissipate the …

During an earthquake, the brace of a multistorey X-braced steel frame experiences out-of-
plane instability. After the brace becomes unstable, the middle span of the brace-intersected …

This paper proposes two novel quasi-X bracing systems to resolve the drawbacks of
concentrically braced frames (CBFs) and enhance their ductility. The seismic performance …

In recent years, the use of structural elements and/or entire structures with low internal
dam** are favoured with the increasing trend for unconventional design of structures and …

A novel hybrid frictional metallic passive damper is introduced in this study. The Piston
Hybrid Frictional Metallic Damper (PHFMD) is equipped with friction pads and steel variable …

Past earthquakes experience regarding frame structures with slender braces, ie tension-only
concentrically braced frames, has demonstrated poor seismic behavior of these systems. In …

Passive energy-dissipating devices or dampers applied as structural fuses are appealing
alternatives to traditional earthquake-resisting design approaches. In this paper, two dual …

This study investigated the story-wise optimal distribution of friction dampers to effectively
reduce the seismic response of a reinforced concrete structure designed without considering …

The structural performance of steel braced frames equipped with a new typology of
dissipative replaceable components (called DRBrC) is analyzed and compared to the one of …

Passive energy dissipation devices have been proved to be effective and low-cost means of
structural control, and a variety of dampers have been developed over the past decades …
