BRB (plural BRBs)

  1. (archaeology) Initialism of bevelled-rim bowl or bevel-rimmed bowl: a small, undecorated, mass-produced clay bowl, most commonly from the 4th millennium B.C.
  2. (engineering) Initialism of buckling-restrained brace: a structural brace in a building or other structure, designed to allow the building to withstand cyclical lateral loadings.

      To provide a more reliable source of energy dissipation, the concept of Buckling-Restrained Brace (BRB) was first developed in Japan in the early 1970s. Extensive research was since conducted in Japan and a variety of BRBs have been developed.

      Moreover, the outer casing is filled with concrete to ensure BRB components remain separated and prevent composite action. Then, BRB brace is submitted into a concentric braced frame, producing a BRBF system.
    • 2018, Alberto Lago, Dario Trabucco, Antony Wood, Damping Technologies for Tall Buildings, page 464:
      The damper mega brace system adds an 8% supplemental damping that helps reduce both wind and seismic excitations. The system is made up of three braces in one (Fig. 6.31B): primary BRB brace and two external secondary BRB braces with viscous dampers at the ends (see Chapter 8, Section 8.1.10 for more details about this building).
