Shake table tests of small- and full-scale laminated timber frames with moment connections

This paper describes the results of shake-table tests of laminated timber frames with moment beam-to-column connections. The objective of the study was to investigate the dynamic behaviour of small-scale (1:4) and full-scale (1:1) frames in regard to residual system deformations and changes in dynamic characteristic due to the progressing damage in the dowel-type connections. Different frame designs with and without connection reinforcement were tested. The experiments demonstrated that the frames were capable of resisting strong ground motions and undergoing large drifts without failure. Moment-resisting frames with correctly designed connections can behave as a self-centering system with columns and beams deforming elastically and connections functioning as energy dissipative links.
