Description

  The present invention relates to an earthquake simulation system for machine rooms such as server rooms and computer rooms.

  An increasing number of companies are developing plans (BCP: Business Continuity Plan) to continue business even in the event of a disaster. In particular, there is an increasing demand for taking countermeasures against earthquakes from the viewpoint of BCP for a server room that houses expensive equipment that manages important data.

  In the server room, a rack is usually installed on a floor such as an OA floor, and servers are stored in the rack. Therefore, in order to take measures against earthquakes, it is necessary to select a construction method and calculate member strength from the calculation of earthquake impact force. However, such a calculation requires the knowledge of a professional engineer and is difficult for a general user to perform.

  In this regard, there has been proposed a system that calculates the amount of damage when an earthquake occurs from information about the structure of a building with a server room and racks (for example, Patent Document 1).

Using the database and the design citation database that stores the numerical values required for calculation, information on the server room and information on the loaded article are read from the server room database and the loaded article specification database, and are generated to correspond to each article. Using the values read from the prepared earthquake countermeasure database and design citation database, the allowable strength of earthquake countermeasures applied to each article is calculated, while the force generated on each article by the earthquake scale arbitrarily specified by the user , And identify the risky part that has an action force that exceeds the allowable strength. Suggest earthquake measures strengthening how the allowable strength in excess, to provide earthquake simulation diagnostic system.

More specifically, the present invention relates to a server room database that stores information related to the server room, a loaded article specification database that stores information related to the loaded article , information related to the OA floor, and information related to earthquake countermeasures for the loaded article. The earthquake countermeasure database that stores data, the design citation database that stores the numerical values necessary for calculation, the information about the server room from the server room database, and the information about the loaded goods loaded on the goods from the loaded goods specification database For each article, use the numerical values read from the earthquake countermeasure database and design citation database generated by the above, and whether the acting force corresponding to the designated earthquake scale acting on the earthquake countermeasure member exceeds the allowable strength of the earthquake countermeasure member. The permissible strength comparison judgment means to judge the When the acting force according to the magnitude of the earthquake exceeds the allowable strength of the earthquake countermeasure member, by increasing the spec of the earthquake countermeasure member sequentially and recalculating, the action corresponding to the designated earthquake magnitude acting on the earthquake countermeasure member There is provided an earthquake simulation diagnosis system comprising: an earthquake strengthening countermeasure proposing means for determining a spec of an earthquake countermeasure member whose force is less than an allowable strength of the earthquake countermeasure member.
