【摘要】 本文介绍了结构预警系统的一般概念、系统状态判别方法以及结构预警系统在广州国际会展中心的应用情况.文中给出的利用实测加速度得到位移并推断结构内力的算法,以及利用加速度谱推断结构动力特性的方法,既有坚实的理论基础,又便于实现,具有很高的实用价值.更多还原

【Abstract】 This paper introduces the basic concept of pre-warning system of structure,the system status identification method and the application situation of the pre-warning system of structure in The International Exhibition Center of Guangzhou.Many useful methods,which both have a solid theoretical basis and are easy to realized,are given in the paper,such as a method to get displacements and structural forces by making use of measured accelerates,a method to infer dynamics characteristic by making use of accelerate spectrum.更多还原
