Seismic performance and standardization of CLT building structures
1Kogakuin University (Japan), 2Kyoto University (Japan)
Cross laminated timber (CLT) is now used worldwide including seismic regions as one of the wood-based building materials suitable not only for low rise buildings but also middle to high rise buildings. Many research projects have been providing findings on seismic performance of CLT structure, by experimental and numerical studies on joints, wall systems and structures, in several countries, Italy, Slovenia, US, Canada, Japan and so on. Besides, the effort has been paid for standardization of seismic design of CLT structures. For example, CNR-Ivalsa (Italy) proposed q-factors in Eurocode 8 based on the shake table tests, and FP Innovations (Canada) proposed R-factors in the National Building Code of Canada and drafted capacity-based procedures in “CLT handbook”. Also in Japan, national research project is now in progress to establish structural design methods which will be a part or supplements of regulations under the Building Standard Law of JAPAN.
This mini-symposium will focus on seismic performance and standardization of CLT building structures. Reports of experimental or numerical studies from several countries will be useful to share the findings, and the discussion on standardization will help harmonization of standards.
