Abstract

There is a tendency that school buildings are constructed with timber construction, because the timber school buildings effectively improve the educational environment. However, the floor impact sound insulation of timber buildings often presents a problem. This paper reports the floor impact sound insulation of the timber three-story school building for final full-scale fire test. The results showed that the heavy-weight floor impact sound insulation using a car-tire source was Lr-65 or 66.2 dBA and the light-weight floor impact sound insulation was Lr-75 or 77.4 dBA. This three-story timber school building was of one-hour quasi-fire-resistive construction with "a reduced section design". Therefore, the building had large-sized girders and beams. Furthermore, the classrooms were arranged in "an open-plan type" with a large volume of sound-receiving room. From the results of the floor impact sound insulation, the effects of reduced section design and open-plan type are considered.
