PROBLEM TO BE SOLVED: To provide a structure capable of restricting a pressure peak generated after breakage of a structurally weak portion by a simple configuration.SOLUTION: A structure 10 includes a structurally weak portion 3. When a combustible gas is mixed into an internal space S of the structure 10 and the combustible gas is burnt, the structurally weak portion 3 is opened, the internal space S and an outer space communicate with each other via the structurally weak portion 3, and a secondary pressure peak is generated in the internal space S after opening of the structurally weak portion 3. An interior material 2 to form the internal space S of the structure 10 is higher in acoustic absorption coefficient than a steel material and the density thereof is higher than 10 kg/m. |
