| Outline of Final Research Achievements |
To revitalize forest and forest products industry in Japan, buildings such as tall office and mass housing made of Japanese ceder in fire protective area are most effective solution. As posts and beams of these buildings must have the fire performance up to three hours, development of two hours fire performance was targeted.
The post or beam for this target consists of load bearing part without any treatment, fire die-out part whose lamina is incised by laser or drill and impregnated a fire retardant, and surface part without any treatment. Three buildings were already built using the certified one hour fire perforamnce post and beam.
The fire die-out part is not adhered, but screwd to loard bearing part in order to replace it easily in case of accidental fire. Two hours fire perforamnce were almost achieved on three times of the fire test. It is found that two hours fire perforamnce can be achieved by a minor change of the design concept.
