Direct displacement-based seismic design of glulam frames with buckling restrained braces. Journal of Earthquake Engineering.1363-2469https://hdl.handle.net/10092/103841This paper presents a direct displacement-based design (DDBD) approach for the buckling restrained braces (BRBs) braced glue-laminated timber (glulam) frame (BRBGF) structures. First, the critical design parameters of the DDBD approach were derived for BRBGFs. Then, using experimentally verified numerical models, pushover analyses and nonlinear time-history analyses (NLTHA) were conducted on a series of one-storey BRBGFs to calibrate the stiffness adjustment factor λ for BRB-timber connections and the spectral displacement reduction factor η. Finally, the DDBD was verified as a prospective approach for the seismic design of multi20 storey BRBGF buildings by NLTHA of the case study buildings.enAll rights reserved unless otherwise statedglulam framesbuckling restrained braces (BRBs)direct displacement-based 22 design (DDBD)BRB-timber connectionsnonlinear time-history analyses (NLTHA)Journal Article2022-06-02Fields of Research::40 - Engineering::4005 - Civil engineering::400504 - Construction engineeringFields of Research::40 - Engineering::4005 - Civil engineering::400510 - Structural engineeringFields of Research::40 - Engineering::4005 - Civil engineering::400506 - Earthquake engineering
