  Damage to buildings such as civil engineering structures and public facilities in the area using the magnitude and probability of occurrence of the earthquake in the area where the fault runs, based on the long-term evaluation information of active fault earthquakes announced by the National Earthquake Research Promotion Headquarters The life cycle cost is calculated considering

  FIG. 3 shows a flow when the computer 1 calculates the life cycle cost of a building such as a civil engineering structure or a public facility in the area. Subsequent to the calculation of the life cycle cost, the damage cost is calculated with reference to the active fault earthquake occurrence probability information 4A, which is one of the hazard maps 3, and the life cycle cost is calculated in consideration of the damage cost.

  In step 101, the computer 1 sets a function level. First, the type of building such as a civil engineering building or a public facility is input by an input device. Civil engineering structures include bridges, dikes, and water pipes. Moreover, location conditions, such as the area (latitude, longitude) of the said building, are input with an input device.

The value obtained by adding.

  The damage cost B1 is a value obtained by multiplying the first and second average repair costs of the civil engineering building by the earthquake occurrence probability within 30 years of the fault in the area (latitude and longitude) where the civil engineering building is built. .

It becomes the value.

  The damage cost C1 is a value obtained by multiplying the total maintenance cost during the life cycle period of the civil engineering structure by the earthquake occurrence probability within 30 years of the fault in the area (latitude, longitude) where the civil engineering structure is built. Therefore, (3) The value including the damage cost C1 when destruction or repair is not necessary but the annual preventive maintenance costs increase is the damage cost C1 added to the life cycle cost of the civil engineering building obtained in step 105 above.

  FIG. 7 shows a flow when the computer 1 calculates the life cycle cost of a building such as a civil engineering structure or a public facility in the area. Following the calculation of the life cycle cost, the damage cost is calculated with reference to the trench earthquake occurrence probability information 4B, which is one of the hazard maps 3, and the life cycle cost is calculated in consideration of the damage cost.

  In step 201, the computer 1 sets a function level. First, the type of building such as a civil engineering building or a public facility is input by an input device. Civil engineering structures include bridges, dikes, and water pipes. Moreover, location conditions, such as the area (latitude, longitude) of the said building, are input with an input device.

  Next, in step 204, a repair rule is set. With reference to the design data in the integrated database 2, the repair cycle and repair cost of the civil engineering structure are obtained. Also ask for annual maintenance costs. Furthermore, the disposal cost after the life cycle of the civil engineering structure is obtained. Steps 201 to 204 are performed as a unit. In the example shown in FIG. 8, 6 years is set as the repair period after the civil engineering building is completed.

  Next, in step 205, a life cycle cost is calculated. The integrated database 2 calculates the life cycle costs of civil engineering structures such as bridges, dikes, and water pipes by integrating initial investment (construction costs), annual maintenance costs, repair costs, and disposal costs. To store.

  As shown in Fig. 8, if a subduction earthquake does not occur, during the life cycle of the civil engineering building, there are annual maintenance costs and periodic repair costs in addition to construction costs. The cost including the disposal cost is the life cycle cost of the civil engineering structure. In the example shown in FIG. 8, construction costs, repair costs in the 6th and 12th years, and annual maintenance in the 1st to 5th years, 7th to 11th years, and 13th to 17th years are shown. The sum of the cost and the disposal cost becomes the life cycle cost of the civil engineering structure.

  In step 206, the trench earthquake damage is evaluated, that is, the damage cost is taken into account. The damage cost is the number of costs (reconstruction, restoration, preventive maintenance, etc.) required when a subduction earthquake occurs during the expected life cycle of a civil engineering structure compared to when it did not occur. It is defined as follows. If a subduction earthquake occurs during this life cycle, civil engineering structures will be damaged, repairs will be required, or annual maintenance costs will increase.

Therefore, (1) the value including the damage cost A2 in the case where the destruction of the civil engineering structure is assumed due to the trench earthquake, the damage cost A2 is added to the life cycle cost of the civil engineering structure obtained in step 205 above. The added value.

  Damage cost B2 was calculated by multiplying the average repair cost for the first and second civil engineering buildings by the earthquake occurrence probability within 30 years in the trench affected by the area (latitude and longitude) where the civil engineering building is built.

  Damage cost C2 is a value obtained by multiplying the total maintenance cost during the life cycle period of the civil engineering structure by the probability of occurrence of an earthquake within 30 years in the trench affected by the area (latitude and longitude) where the civil engineering structure is built. It becomes. Therefore, (3) The value including the damage cost C2 when destruction or repair is not necessary but the annual preventive maintenance costs increase is calculated by adding the damage cost C2 to the life cycle cost of the civil engineering structure obtained in step 205 above. The added value.

  FIG. 10 shows a flow when the computer 1 calculates the life cycle cost of a building such as a civil engineering structure or a public facility in the area. Following the calculation of the life cycle cost, the damage cost is calculated with reference to the volcanic eruption activity probability information 4C, which is one of the hazard maps 3, and the life cycle cost is calculated in consideration of the damage cost.

  In step 301, the computer 1 sets a function level. First, the type of building such as a civil engineering building or a public facility is input by an input device. Civil engineering structures include bridges, dikes, and water pipes. Moreover, location conditions, such as the area (latitude, longitude) of the said building, are input with an input device.

In the example shown in FIG. 11, 6 years is set as the repair period after the completion of the civil engineering structure.

  Next, in step 305, a life cycle cost is calculated. The integrated database 2 calculates the life cycle costs of civil engineering structures such as bridges, dikes, and water pipes by integrating initial investment (construction costs), annual maintenance costs, repair costs, and disposal costs. To store.

  As shown in FIG. 11, if a volcanic eruption does not occur, during the life cycle of the civil engineering building, there are annual maintenance costs and periodic repair costs in addition to the construction costs. The cost including the disposal cost is the life cycle cost of the civil engineering structure.

FIG. 15 is a graph showing the life cycle cost representing the relationship between the building time (year) and the cost by the maintenance management planning system according to Embodiment 4 of the present invention.

  Based on the information on the probability of heavy rain and typhoon attacks announced by the Japan Meteorological Agency and local governments, life in consideration of damages such as flooding due to flood storm surge, destruction by storms, destruction due to landslides, etc. Calculate the cycle cost.

  FIG. 14 shows a flow when the computer 1 calculates the life cycle cost of a building such as a civil engineering building or a public facility in the area. Following the calculation of the life cycle cost, the damage cost is calculated with reference to the concentrated heavy rain occurrence probability information 4D, which is one of the hazard maps 3, and the life cycle cost is calculated in consideration of the damage cost.

  In step 401, the computer 1 sets a function level. First, the type of building such as a civil engineering building or a public facility is input by an input device. Civil engineering structures include bridges, dikes, and water pipes. Moreover, location conditions, such as the area (latitude, longitude) of the said building, are input with an input device.

  Next, in step 402, the deterioration process is set. Referring to the design data in the integrated database 2, etc., considering the deterioration of concrete, moving parts, etc., for example, obtaining the life cycle (lifetime) of the civil engineering structure such as a bridge, a dike, a water pipe, etc. . In the example shown in FIG. 15, 17 years is set as the life cycle after completion of the civil engineering structure.

  Next, in step 403, the expense is set. The initial investment (construction cost) of the civil engineering building is obtained with reference to the business data in the integrated database 2.

  Next, in step 404, a repair rule is set. With reference to the design data in the integrated database 2, the repair cycle and repair cost of the civil engineering structure are obtained. Also ask for annual maintenance costs. Furthermore, the disposal cost after the life cycle of the civil engineering structure is obtained. Steps 401 to 404 are performed as a unit. In the example shown in FIG. 15, 6 years is set as the repair cycle after the civil engineering building is completed.

  Next, in step 405, the life cycle cost is calculated. The integrated database 2 calculates the life cycle costs of civil engineering structures such as bridges, dikes, and water pipes by integrating initial investment (construction costs), annual maintenance costs, repair costs, and disposal costs. To store.

  As shown in FIG. 15, if there is no torrential rain, there are annual maintenance costs and regular repair costs in addition to the construction costs during the life cycle of the civil engineering building. The cost including the disposal cost is the life cycle cost of the civil engineering structure. In the example shown in FIG. 15, construction costs, repair costs in the 6th and 12th years, and annual maintenance in the 1st to 5th years, 7th to 11th years, and 13th to 17th years. The sum of the cost and the disposal cost becomes the life cycle cost of the civil engineering structure.

  In step 406, concentrated heavy rain damage is evaluated, that is, the damage cost is taken into account. The damage cost is the number of times (reconstruction, restoration, preventive maintenance, etc.) required when a heavy rain occurs during the assumed life cycle period of a civil engineering structure compared to when it does not occur. It is defined as follows. If heavy rain occurs during this life cycle, the civil engineering structure will be damaged, repairs will be required, or annual maintenance costs will increase. The damage cost considered in this step is (1) When the target civil engineering building is completely destroyed, (2) When the function can be restored by repair, (3) When the annual maintenance can be overcome by preventive maintenance, Define each damage cost in 3 cases. The obtained damage cost and the life cycle cost considering the damage cost are stored in the integrated database 2.

(1) In the case of total destruction of the target due to storms, floods, landslides, etc. due to storms, typhoons, etc. Damage cost A4 = Construction cost x Probability of storms during the life cycle

(2) In the case where it is assumed that repairs and repairs can be handled without complete destruction Damage cost B4 = repair cost per repair × probability of occurrence of concentrated heavy rain during the life cycle

(3) When destruction or repair is not necessary due to strong winds, inundation, storm surges, etc., but annual preventive maintenance costs increase Damage cost C4 = total preventive maintenance costs during the life cycle × probability of occurrence of concentrated heavy rain during the life cycle

  The damage cost A4 is a value obtained by multiplying the construction cost of the civil engineering building by the probability of occurrence of concentrated heavy rain within 30 years that affects the area (latitude and longitude) where the civil engineering building is built. Therefore, (1) the value including the damage cost A4 in the case of total destruction of the civil engineering building due to the heavy rain, the damage cost A4 is added to the life cycle cost of the civil engineering building obtained in step 405 above. The added value.

  Damage cost B4 was calculated by multiplying the average repair cost for the first and second civil engineering buildings by the probability of occurrence of a torrential rain within 30 years that affects the area (latitude and longitude) where the civil engineering building is built. Value. Therefore, (2) The value including the damage cost B4 in the case where it is assumed that it can be dealt with by restoration and repair without being completely destroyed is added to the life cycle cost of the civil engineering building obtained in the above step 405. It becomes the value.

  The damage cost C4 is a value obtained by multiplying the total maintenance cost during the life cycle period of the civil engineering building by the probability of occurrence of concentrated heavy rain within 30 years affected by the area (latitude and longitude) where the civil engineering building is built. It becomes. Therefore, (3) The value including the damage cost C4 when destruction or repair is not necessary but the annual preventive maintenance costs increase is calculated by adding the damage cost C4 to the life cycle cost of the civil engineering structure obtained in step 405 above. The added value.

  In addition, (1) When the target civil engineering building is completely destroyed, (2) When the function can be restored by repair, (3) The case of 3 cases where the annual maintenance can be overcome by proactively conserving, the case classification is concentrated This is based on the “maximum precipitation amount” of torrential rain that affects the area (latitude, longitude) in which the civil engineering building is built in the heavy rain occurrence probability information 4D.

  As shown in FIG. 12, the computer 1 displays the damage cost obtained by the civil engineering structure such as a bridge, a dike, a water pipe, and the like in the map display window display area 6 of the display device 5 by the damage cost display operation of the input device. The life cycle cost including the damage cost of the civil engineering building as shown in FIG. 15 is displayed on the display device 5 by the life cycle cost display operation of the input device.

  As described above, the damage probability of an object is evaluated by utilizing the probability of heavy rains and typhoons, so the accuracy of calculating the life cycle cost of buildings and public facilities in the area is improved, and more effective based on this. Effective maintenance plan.
