Seismic design and behaviour of innovative timber systems
1University of L'Aquila (Italy), 2Colorado State University (USA), 3Kyoto University (Japan)
Timber is a lightweight material and, as such, performs particularly well in moderate to intense earthquakes. However wood itself is not ductile and may have brittle failure modes such as splitting if not addressed properly within the seismic design procedure. Extensive research has been completed and numerous projects are underway worldwide on the seismic behavior of timber structures and buildings. An effort has been made to implement this new knowledge in codes of practice such as the Eurocode and the Canadian Standard. Many countries have differing design philosophies and rules governing the number of stories, the approach used for overstrength, etc. This mini-symposium will highlight the results of research projects from Italy, the United States, Germany, Japan, Canada, New Zealand, Slovenia, France, and Portugal. This includ3es experimental testing and numerical modelling of connections, subassemblies and full-scale building tests; some light-frame will be presented but the majority of the focus will be on heavier timber technologies such as cross-laminated, glue-laminated, log-house and hybrid construction; and the use of innovative techniques such as tuned mass dampers, energy dissipaters, post-tensioning and passive base isolation in timber buildings. The development of design methods including capacity based design will be also the subject of the Symposium.
