Wellington: NZSEE 2022 Annual Conference. 27/04/2022-29/04/2022. Proceedings of the 2022 NZSEE Conference.https://hdl.handle.net/10092/103853This paper describes a simple method for BRB system design considering BRB stability and frame out-ofplane deformation effects. The method seeks to prevent yielding in the BRB system except for in the core within the BRB restrainer/casing, and it uses standard equations with which engineers are familiar. The method discourages brace/gusset plate regions which are too flexible, where instability may occur as a result of axial force, or which are too stiff, where yielding may occur due to out-of-plane frame deformations thereby compromising the performance in later in-plane deformation cycles. The need to explicitly consider column twist restraint in the design procedure is emphasized.enAll rights reserved unless otherwise statedConference Contributions - Published2022-06-14Fields of Research::40 - Engineering::4005 - Civil engineering::400504 - Construction engineeringFields of Research::40 - Engineering::4005 - Civil engineering::400506 - Earthquake engineering
