Two-level Buckling Restrained Brace (DBRB)

Two-level Buckling Restrained Brace (DBRB) - DBRB Introduction

DBRB Introduction

A staged BRB system that provides stiffness and energy dissipation under small, moderate, and major earthquakes. First-stage dampers work under smaller events, while the second-stage BRB yields under stronger events.

DBRB Introduction 2

Under small earthquakes, the first-stage damper yields and dissipates energy while the BRB remains elastic. Under moderate earthquakes, both stages participate. Under major earthquakes, the BRB continues to protect the main structure.

DBRB Introduction 3

Steel Damper friction-type DBRB can remain effective under major deformation and may not require replacement after post-earthquake inspection.

DBRB Introduction 4

A staged BRB system that provides stiffness and energy dissipation under small, moderate, and major earthquakes. First-stage dampers work under smaller events, while the second-stage BRB yields under stronger events.

Connection Type

DBRB uses the same major connection types as BRB: bolted, welded, and pinned connections, selected according to project precision, installation efficiency, and economy requirements.

Connection Type 2

A staged BRB system that provides stiffness and energy dissipation under small, moderate, and major earthquakes. First-stage dampers work under smaller events, while the second-stage BRB yields under stronger events.
