PROBLEM TO BE SOLVED: To provide a suspended ceiling structure in which aseismic performance can be improved by surely presenting effects of a reinforcing brace in earthquakes.SOLUTION: A suspended ceiling structure comprises a horizontal member 15, and a reinforcing brace 14. The horizontal member 15 extends along another direction T2 while being placed on a plurality of ceiling joist holders 2 and is disposed while being connected to the plurality of ceiling joist holders 2. The reinforcing brace 14 is disposed by connecting one end 14a to the horizontal member 15 and another end 14b to an upper structure directly or indirectly, respectively. The suspended ceiling structure further comprises an aseismic reinforcement member 20 which connects the horizontal member 15 and a ceiling member 4. |
