DEVELOPMENT OF QUASI-FIREPROOF BUILDINGS BY WOODEN POST & BEAM CONSTRUCTION

点击翻译按钮获取中文摘要

Engineering design method and design examples of load-bearing members such as external walls, room partitions and floor-beam assemblies of Japanese traditional bare-timber construction are presented. Full-scale and small scale fire resistance tests on these members were conducted to develop and verify predictive method for their post-fire integrity and load-bearing capacity The study revealed significance of the long-term loading on the post-fire mechanical performance of these members, which indicates need of structural design based on occupancy consideration. The predictive method has been applied to the structural and fire safety design of a three-story traditional style townhouse and a two-story large nursery facility.
