Full-Scale Shake Table Testing of Cross-Laminated Timber Rocking Shear Walls with Replaceable Components
Publication: Journal of Structural Engineering
Volume 145, Issue 10
Abstract
To investigate and validate the seismic performance of a new cross-laminated timber rocking shear wall lateral system, a series of shake table tests were conducted on a full-scale, two-story, mass timber building at the NHERI@UCSD outdoor shake table facility. The prototype wall system was designed to remain damage-free during frequent service level earthquakes and repairable after larger events [design basis earthquakes (DBEs) and maximum considered earthquakes (MCEs)] while utilizing replaceable components that enable quick repair after a large earthquake. The test building was subjected to a series of 13 earthquake ground motions and reached a maximum roof drift of 3.85%. Following shake table tests at the DBE and MCE levels, the building was inspected and repaired by replacing the damaged energy absorbing components. The test data demonstrated that the proposed system was able to achieve the desired seismic performance (i.e., repairable) and also effectively control building deformation under code-specified levels at DBE- and MCE-level events.
