specific Embodiment approach 1

[0030] Specific implementation mode one: a kind of residential house earthquake damage matrix dynamic prediction method of the present implementation mode, the specific process is:

[0031] The sample data can adopt the method of coexistence of earthquake damage prediction data and actual earthquake cases to meet the diversity of data. Considering that the current urban buildings are mainly brick-concrete structures, multi-storey reinforced concrete structures, and high-rise structures, it is recommended to distinguish them mainly by structure types when constructing the urban building database. See image 3 .

[0032] The samples in the sample database must first be tested for integrity. Whether a single sample has no data for parameters or a wrong data format, the format of the data that requires calculations is generally selected as a value. Then check its logic to see if the result makes sense. The discreteness of the sample data is equally important. The amount of data ...

specific Embodiment approach 2

[0046] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: in the step 3, the values ​​of i are 1, 2, 3, 4, 5, 6 and 7; d ij The i-th earthquake damage factor that meets the classification of item j is specifically:

[0047] For brick-concrete structures:

[0048] When the value of i is 1, the earthquake damage factor is the fortification intensity, and the number of fortification intensity categories M is 3 categories:

[0049] 1), VI degree and below, d ij 1.5; 2), VI degrees, d ij 1.1; 3), VII degree, d ij is 0.95;

[0050] When the value of i is 2, the earthquake damage factor is the site environment, and the number of site environment categories M is 3 categories:

[0051] 1), favorable location, d ij is 1.0; 2), unfavorable location, d ij is 1.8; 3), dangerous area, d ij is 2.8;

[0052] When the value of i is 3, the seismic damage factor is the site type, and the number of site types M is 4 categories:

[0053] 1), Class...

specific Embodiment approach 3

[0108] Specific implementation mode three: the difference between this implementation mode and specific implementation mode one or two is: the calculation of each type of earthquake damage factor in the step four is specifically:

[0109]

[0110] In the formula, d ij is the i-th earthquake damage factor that meets the classification of item j; m ij is a power exponent, which takes 1 when the situation of the i-th earthquake damage factor meets the j-th classification, and takes 0 for the rest.

[0111] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to a city building group seismic hazard matrix dynamic prediction method. The method aims at solving the problems that any designated region cannot be dynamically displayed through related method since the different years, different floor numbers and other conditions of the residence community in the city are incompletely considered in the prior art. The specific process is as follows: step one, determining a structure type of the building; step two, determining and computing seismic hazard factors and the number N thereof of the building structure types in different regions; step three, determining dij, Omega and T; step four, computing each type of seismic hazard factor; step five, computing the total seismic hazard factor; step six, computing Lambda; step seven, computing D; step eight, determining the damage level of single building or community; step nine, computing the damage levels of all single buildings or communities needing to be computed, and not computing the computed damage levels; and step ten, dynamically providing a corresponding seismic hazard matrix in combination with computer software. The method disclosed by the invention is used for the seismic hazard prediction field of the building structure.

Description

technical field [0001] The invention relates to a dynamic prediction method of an urban building group earthquake damage matrix. Background technique [0002] The detection shows that among the provincial capital cities of my country's 34 administrative regions, at least 21 cities have seismogenic active faults and have the potential danger of near-field strong earthquakes. More than 2,000 cities and towns across the country are always facing the threat of catastrophic earthquakes! There is a clear contradiction between the demand for safety in the rapid economic development and the threat of severe earthquake disasters faced by the majority of cities in our country. Judging, unfortunately, although there are many earthquake damage prediction methods and results for buildings, each method has its own advantages and disadvantages, and it is imperfect to consider the different ages and floors of residential quarters in cities. At the same time, combined with display software...
