| Abstract: | The present paper focuses on automatically extracting the characteristic parametersof response spectrum based on neural network method. The application model established isfirst trained using some sample data to accumulate "knowledge", and then it extracts thecharacteristic parameters of the new input vector automatically by means of the obtained"knowledge". The input of the model is earthquake response spectrum, and the output of themodel is some characteristic parameters, such as the shape parameters of response spectrum,period value of Tg, platform width of standard spectrum, etc. In this paper, the model andmethod about extracting shape parameters of response spectrum is described. An example isshown and computing experiment is made. According to above mentioned method some similarmodels can be designed and developed. |
