The Research Of A Fast Earthquake Disaster Prediction Method For City's Common Buildings

The historical earthquake damage indicated that the destruction of buildings is themain destruction form in the earthquake in a city. The destruction of buildings results inthe losing of economy, the death of people, the happening of secondary disaster and so on.Accordingly, the most effective methods to improve the synthetic ability of earthquake-resistance and release the damage to the maximum degree of a city are as followings:predicting the earthquake disaster of buildings as earthquake happened scientifically;analyzing the weak point in the earthquake-resistance and damage prevention of a city andputting forward the defending strategies pertinently.This thesis emphasized on the following works:Introduced the results of earthquake disasters in cities and the meaning of earthquakedamage prediction; Described the history and futural trends of earthquake damageprediction for buildings, introduced the traditional methods and its character in earthquakedamage prediction, pointed out that it is significant to analysis the fast earthquake disasterprediction method; On the basis of prediction for earthquake damage using analogicalmethod, put forward a fast earthquake disaster prediction method and worked out thecorresponding procedure. Summarized some previous earthquakes, selected the earthquakeinstances to set up the sample storehouse. Utilized the traditional vulnerability analyticalmethods , carryed on vulnerability analysis to the ubiquitous typical structure typebuildings of our country, expanded the sample storehouse. Regard this database as theknowledge of the earthquake disaster, after getting the similar sample through theHamming distance, calculated the earthquake disaster index of the buildings through thethe average value; Seted up the BP neural network model, and used the net to study theknowledge in the sample storehouse, predicted the earthquake disaster of the investigatedhouses; Took Quanzhou city as an example, utilizing the method of this thesis to carry onthe work of earthquake disaster prediction for parts of its common buildings.After the calculation, taking Quanzhou city's buildings as an example, testified thatthe way this article discussed is feasible.
