Final Report of a Research and Development Project on Timber-based Hybrid Building Structures

Since 1999, a research and development project on timber-based hybrid structures has been promoted in Japan as a five-year national project. The objectives of this project are to develop high-performance timber-based composite members and timber-based hybrid structures, which consist of timber and other materials, to develop the evaluation methods of structural performance and fireproof performance for these structures, and to develop the design method for some typical timber-based hybrid structures. As a final report of this research and development project, outline of research items, some of the research findings, and outline of proposed performance evaluation methods are summarized in this paper.
