DEVELOPMENT OF FIRE RESISTIVE SEPARATING CONSTRUCTION CONSISTING OF STEEL BEAM AND FIREPROOF PARTITION WALL

Abstract

A separating construction consisting of steel beam and fireproof partition wall is developed. In the development of the construction, a full scale fire test and small scale fire tests are carried out in order to verify two performances. One performance is the interaction between beam and partition wall, and the other is thermal insulation capacity. As the result of tests, it is confirmed that the beam-wall interaction is not a problem, and that thermal insulation capacity depends on the temperature of beam. According to these results, a simplified calculation method of temperature on non-heated side of steel beam is proposed.
