一种支持自动化选波的地震波数据库系统
摘要
近年来地震频发,建筑结构的抗震性越来越被人们所重视,因此如何选取需要的地震波来检测建筑结构变得非常重要.虽然欧美等国家已经建立了一些用于结构抗震研究的地震波数据库系统,但是这些数据库系统均未能涵盖能反映我国地震动特征的地震波,也未能提供满足我国工程设计的选波方法,更没有实现自动化选波,所以迅速开发我国自己的地震波数据库系统和研究科学合理的选波方法显得十分必要.设计并实现了一种可以自动化选波的地震波数据库系统,该系统收集了许多具有代表性和权威性的地震波,并支持条件选波和最不利选波.大量的实验表明,该地震波数据库系统的选波效率、选波结果均能满足用户的要求.
With many earthquakes happening in recent years,the seismic performance of building structures is more and more important.How to select earthquake ground motion records for testing buildings is becoming much more necessary.Although the occident has set up some earthquake ground motion database systems for researches of seismic performance of building structures,these database systems are not able to cover characteristics of earthquake ground motions of our country,nor offer record election methods meeting requirements of our engineering designs,let alone the automatic record selection method.Therefore,it is much necessary to develop an earthquake ground motion database system and scientific and reasonable selection methods of our country immediately.This paper presents an earthquake ground motion database system,which collects a lot of earthquake ground motion records.And the system supports two kinds of earthquake ground motion record selection methods:the conditional ground motion selection method and the severest ground motion selection method.Many experiments prove that the efficiency and effects of earthquake ground motion record selection methods can both meet users' requirements.
