[0033] For ease of understanding, the following describes the calculation method for the seismic performance of a nuclear safety building according to the first embodiment of the present invention. Figure 1 As shown, the method for calculating the seismic performance of a nuclear safety building in the first embodiment of the present invention includes steps S110 to S160.

[0034] In step S110, the initial load resistance ratio of the most unfavorable component of the building to be inspected is obtained.

[0035] In this embodiment, the building to be inspected is a nuclear safety building to be inspected. Since the nuclear safety building to be inspected generally includes multiple components with different structures, before calculating the seismic performance of the building to be inspected, the design parameters of all components of the building to be inspected are obtained or a simulation model of all components of the building to be inspected is constructed, and the load effects and resistance of all components are calculated under fixed seismic parameters, and then the ratio of the load effect to the resistance effect of each structure, that is, the initial load-resistance ratio, is determined.

[0036] Among them, the component with the largest initial load-resistance ratio is the most unfavorable component of the building to be tested.

[0037] In step S120, based on the incremental dynamic analysis method, the failure probability values ​​corresponding to multiple nuclear safety buildings under the original design seismic parameters are calculated respectively under seismic waves of different amplitudes.

[0038] like Figure 2 As shown, in some optional embodiments, step S120 includes steps S121 to S126.

[0039] In step S121, a plurality of seismic waves matching the response spectrum of each nuclear safety building are obtained.

[0040] In step S122, a building structure model corresponding to each nuclear safety building is constructed.

[0041] In step S123, based on the incremental dynamic analysis method, the building structure model is controlled to perform simulation detection under earthquake waves of different amplitudes to generate simulation detection results including multiple simulation curves.

[0042] In step S124, the seismic performance threshold of each nuclear safety building is obtained, and the failure point of each simulation curve is determined according to the seismic performance threshold.

[0043] In step S125, based on the failure point of each simulation curve, a failure probability distribution curve under seismic waves of different amplitudes is generated.

[0044] In step S126, based on the failure probability distribution curve, the failure probability value corresponding to each nuclear safety building is obtained.

[0045] In a specific embodiment of the present invention, firstly, three or more nuclear safety buildings constructed at the same time as the building to be inspected are selected, and a building structure model corresponding to each nuclear safety building is constructed by finite element software according to the material properties, geometric dimensions and boundary conditions of the nuclear safety buildings. In addition, the number of seismic waves of different intensities that match the response spectrum of each nuclear safety building is 20 or more. After completing the construction of the building structure model corresponding to each nuclear safety building and the selection of the corresponding seismic wave, an IDA (Incremental Dynamic Analysis) analysis is performed on each building structure model, and the seismic wave amplitude is gradually scaled in all selected seismic waves, and a nonlinear time history analysis is performed to obtain the structural response of each analysis under each seismic wave, so as to determine the failure probability distribution curve of each building structure model, and finally form a curve cluster of each building structure model.

[0046] Then, according to the failure point of each failure probability distribution curve, the failure probability of the nuclear safety building under earthquake waves of different intensities is determined, and a failure probability distribution diagram is formed by fitting, and finally the corresponding failure probability value of each nuclear safety building is determined.

[0047] In step S130 , a first adjustment coefficient is obtained based on the failure probability value.

[0048] like Figure 3 As shown, in some optional embodiments, step S130 includes steps S131 to S132.

[0049] In step S131, based on the corresponding failure probability values ​​of all nuclear safety buildings, the average failure probability value of the nuclear safety buildings is calculated.

[0050] In step S132, a first adjustment coefficient is obtained based on the average failure probability value.

[0051] In this embodiment, the corresponding failure probability value of each nuclear safety building obtained according to the above steps is averaged to obtain the average failure probability value of all nuclear safety buildings, and then the first adjustment coefficient is obtained.

[0052] Specifically, the first adjustment coefficient is calculated based on the following formula:

[0053] =10 -5 / ;

[0054] in, is the first adjustment coefficient, is the average failure probability value.

[0055] In step S140, a sampling test is performed on all components of the building to be tested, and a second adjustment coefficient is obtained based on the sampling ratio and the test result of the building to be tested.

[0056] like Figure 4 As shown, in some optional embodiments, step S140 includes steps S141 to S143.

[0057] In step S141, a sampling test is performed on the strength values ​​of all components in the building to be tested to obtain the test results corresponding to the components.

[0058] In step S142, a corresponding sampling coefficient is obtained based on the sampling ratio in the building to be detected.

[0059] In step S143, a second adjustment coefficient is obtained based on the detection result and the sampling coefficient.

[0060] In this embodiment, the test results include the actual calculated strength value and the design strength value of the tested component. The actual calculated strength value can be obtained by performing strength testing on the component and calculating its strength value according to the tested construction parameters. The design strength value is a preset strength value of the tested structure. The sampling coefficient is selected through a sampling coefficient table corresponding to different sampling ratios as shown in Table 1.

[0061] The sampling coefficients corresponding to different sampling ratios are shown in Table 1.

[0062] Table 1

[0063]

[0064] Among them, n is the sampling coefficient corresponding to different sampling ratios.

[0065] The second adjustment coefficient is calculated by the following formula:

[0066] ;

[0067] in, is the actual calculated strength value of the component being tested, is the preset strength value of the component being tested, n is the sampling coefficient, is the second adjustment factor.

[0068] In step S150, a third adjustment coefficient is obtained based on the natural vibration period of the building to be detected and the natural vibration period of the equipment supporting structure in the building to be detected.

[0069] like Figure 5 As shown, in some optional embodiments, step S150 includes steps S151 to S153.

[0070] In step S151, based on the natural vibration period of the building to be detected and the natural vibration period of the equipment supporting structure in the building to be detected, the natural vibration period ratio of the natural vibration period of the building to be detected and the natural vibration period of the equipment supporting structure in the building to be detected is obtained.

[0071] In step S152, the mass ratio of the building to be inspected and the equipment supporting structure in the building to be inspected is obtained.

[0072] In step S153, a third adjustment coefficient is obtained based on the natural oscillation period ratio and the mass ratio.

[0073] In this embodiment, the third adjustment coefficient Select according to Table 2 and Table 3 shown below.

[0074] Table 2 (mass ratio 0.01)

[0075]

[0076] Table 3 (mass ratio 0.1)

[0077]

[0078] As shown in Table 2 and Table 3, Table 2 is a table showing the relationship between the natural vibration period ratio and the third adjustment coefficient when the mass ratio of the building to be detected to the equipment support structure in the building to be detected is 0.01, and Table 3 is a table showing the relationship between the natural vibration period ratio and the third adjustment coefficient when the mass ratio of the building to be detected to the equipment support structure in the building to be detected is 0.1. That is, when the calculated values ​​of the natural vibration period ratio and the mass ratio of the natural vibration period of the building to be detected to the natural vibration period of the equipment support structure in the building to be detected are the values ​​shown in Table 2 and Table 3, the corresponding third adjustment coefficient can be directly selected. .

[0079] Further, in step S153, when the mass ratio is between the first mass threshold and the second mass threshold and / or when the natural oscillation period ratio is between the first natural oscillation period threshold and the second natural oscillation period threshold, a third adjustment coefficient corresponding to the natural oscillation period ratio and the mass ratio is obtained based on linear interpolation.

[0080] In this embodiment, if the calculated values ​​of the natural vibration period ratio and the mass ratio of the natural vibration period of the building to be inspected and the natural vibration period of the equipment supporting structure in the building to be inspected are not the values ​​shown in Tables 2 and 3, for example, the natural vibration period ratio is between 0.5 and 1, between 1 and 1.5, or between 2 and 3, and the mass ratio is between 0.01 and 0.1, for example, the mass ratio is 0.03, then the linear interpolation method is used to calculate the third adjustment coefficient corresponding to the natural vibration period ratio and the mass ratio.

[0081] For example, when the calculated mass ratio is 0.03 and the natural vibration period ratio is 1, the third adjustment coefficient is calculated based on the linear interpolation method according to the following formula: .

[0082] ;

[0083] Where m is the corresponding mass ratio of 0.03, The mass ratio in Table 2 is 0.01, The mass ratio in Table 3 is 0.1, is the third adjustment coefficient when the natural vibration period ratio is 1 under the corresponding mass ratio of 0.01 , which is 1.21, is the third adjustment coefficient when the natural vibration period ratio is 1 under the corresponding mass ratio of 0.1 , which is 1.26.

[0084] Substituting all the parameters into the formula, we can get that when the calculated mass ratio is 0.03 and the natural vibration period ratio is 1, the third adjustment coefficient is 1.221.

[0085] By means of linear interpolation, when the calculated natural vibration period ratio and mass ratio are within the parameter range of the table, the third adjustment coefficient can be determined more accurately, thereby ensuring the accuracy of the calculated seismic evaluation results of the building to be tested.

[0086] In step S160, based on the initial load-resistance ratio, the first adjustment coefficient, the second adjustment coefficient and the third adjustment coefficient, a seismic evaluation result of the building to be inspected is generated.

[0087] In some optional embodiments, the seismic evaluation result is obtained based on the following formula:

[0088] ;

[0089] Among them, R is the final load resistance ratio of the seismic evaluation result, is the initial load resistance ratio, k1 is the first adjustment coefficient, k2 is the second adjustment coefficient, and k3 is the third adjustment coefficient.

[0090] In this embodiment, the calculated initial load-resistance ratio of the most unfavorable component of the building to be tested is respectively equalized with the first adjustment coefficient, the second adjustment coefficient and the third adjustment coefficient, and finally the final load-resistance ratio of the building to be tested is obtained to obtain the seismic evaluation result of the building to be tested, and determine whether the actual seismic performance of the building to be tested can meet the preset seismic performance.

[0091] Figure 6 This is a flow chart of the second embodiment of the method for calculating the seismic performance of nuclear safety buildings of the present invention. Part of the structure of the second embodiment is the same as that of the first embodiment, and the differences between the two will be described below, and the similarities will not be described in detail.

[0092] like Figure 6 As shown, in the second embodiment of the present invention, the method for calculating the seismic performance of a nuclear safety building includes steps S210 to S290, wherein steps S210 to S260 are the same as the method for calculating the seismic performance of a nuclear safety building in the first embodiment of the present invention, and will not be repeated in this application.

[0093] In step S210, the initial load resistance ratio of the most unfavorable component of the building to be inspected is obtained.

[0094] In step S220, based on the incremental dynamic analysis method, the failure probability values ​​corresponding to multiple nuclear safety buildings under the original design seismic parameters are calculated respectively under seismic waves of different amplitudes.

[0095] In step S230, a first adjustment coefficient is obtained based on the failure probability value.

[0096] In step S240, a sampling test is performed on all components of the building to be tested, and a second adjustment coefficient is obtained based on the sampling ratio and the test result of the building to be tested.

[0097] In step S250, a third adjustment coefficient is obtained based on the natural vibration period of the building to be detected and the natural vibration period of the equipment supporting structure in the building to be detected.

[0098] In step S260, based on the initial load-resistance ratio, the first adjustment coefficient, the second adjustment coefficient and the third adjustment coefficient, a seismic evaluation result of the building to be inspected is generated.

[0099] After generating the seismic evaluation results of the building to be inspected, the method for calculating the seismic performance of a nuclear safety building further includes steps S270 to S290.

[0100] In step S270, based on the seismic evaluation result, the final load-resistance ratio of the building to be inspected is obtained.

[0101] In step S280, based on the final load-resistance ratio, the seismic performance deviation value of the building to be tested is obtained.

[0102] In step S290, based on the seismic performance deviation value, it is determined whether the seismic performance of the building to be inspected is greater than the deviation threshold. If it is greater than the deviation threshold, the building to be inspected is reinforced. If it is less than the deviation threshold, the building to be inspected meets the preset seismic performance requirements.

[0103] In this embodiment, the deviation threshold and the preset anti-seismic performance deviation value are 5%, that is, the deviation threshold is 95%. The deviation threshold can also be other values, which are not limited in this application. For example, as shown in the following formula:

[0104] ;

[0105] Among them, R is the final load resistance ratio of the seismic evaluation result, is the initial load resistance ratio, k1 is the first adjustment coefficient, k2 is the second adjustment coefficient, and k3 is the third adjustment coefficient.

[0106] When the calculated final load-resistance ratio R≥1, it proves that the seismic performance of the building to be tested meets the preset seismic performance; when the calculated final load-resistance ratio is 0.95≤R≤1, it proves that the seismic performance of the building to be tested is within the deviation threshold, and the seismic performance of the building to be tested will not cause hidden dangers; when the calculated final load-resistance ratio R<0.95, it proves that the seismic performance of the building to be tested does not meet the preset seismic performance requirements, and the building to be tested needs to be reinforced.

[0107] The method for calculating the seismic performance of a nuclear safety building provided in an embodiment of the present invention includes: obtaining the initial load-resistance ratio of the most unfavorable component of the building to be tested; based on the incremental dynamic analysis method, respectively calculating the failure probability values ​​corresponding to multiple nuclear safety buildings under the original design seismic parameters under seismic waves of different amplitudes; obtaining a first adjustment coefficient based on the failure probability value; performing sampling inspection on all components in the building to be tested, and obtaining a second adjustment coefficient based on the sampling ratio and inspection results of the building to be tested; obtaining a third adjustment coefficient based on the natural vibration period of the building to be tested and the natural vibration period of the equipment supporting structure in the building to be tested; and generating a seismic evaluation result of the building to be tested based on the initial load-resistance ratio, the first adjustment coefficient, the second adjustment coefficient and the third adjustment coefficient.
