| Research Abstract |
Although present fire resistance design rules out the displacement of buildings, this is not true in practice. In fact, local displacements of heated members and the vicinities are generally not small. In view of this, a study is made on the interactive behaviors of load bearing and thermal insulating members of steel structures subjected to fire. The maximum displacements which heated steel frames can bear stably in fire have been clarified analytically. Two series of full scale tests have been also conducted to see whether insulation members can follow the above displacements. One is the heating test of displaced gypsum board walls. Another is simultaneous loading and heating test of protected steel box columns, where sprayed rock wool, rock wool felt sheet and calcium silicate plates were chosen for protection materials.
