Then, the building damage determination unit 20 determines how much the equipment has been damaged in accordance with the degree of change in elasticity.

According to this embodiment, in order to correct the acceleration response Sa in the graph of the acceleration response spectrum based on the third acceleration information (the third sensor 4 or the fourth sensor 5) in which the building 100 is actually vibrating, Vibration can be reflected, and the soundness of the building 100 can be determined with higher accuracy than each of the first embodiment and the second embodiment.
Further, according to the present embodiment, the measured natural period measured after the earthquake and the measured before the earthquake based on the third acceleration information (the third sensor 4 or the fourth sensor 5) in which the building 100 is actually vibrating. Since the elasticity of the building 100 is detected by comparing with the confirmed natural period and the degree of damage to the equipment of the building 100 is determined based on this elasticity, the degree of damage to the equipment can be easily estimated.

It should be noted that a program for realizing each function of the response analysis apparatus 1, 1 ′, 1 ″ in the present invention is recorded on a computer-readable recording medium, and the program recorded on the recording medium is stored in a computer system. You may control the process which confirms the soundness of a building by making it read and performing. Here, the “computer system” includes an OS and hardware such as peripheral devices.
The “computer system” includes a WWW system having a homepage providing environment (or display environment). The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included.

  The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.
