摘要

基于振动测量的结构健康监测是一个实现传感器和方法仪器的过程,以提供有关结构状况的信息,从而评估结构系统的安全性和完整性。正因为如此,在过去的几十年里,已经开发了几种算法;其中,小波变换被认为是消除传感器记录的加速度中包含的误差的有效方法。然而,由于地震的复杂性和结构系统的特殊性,小波变换在地震响应中用于消除误差的参数经常是可变的。本文提出了一种方法,通过对结构数学模型的数值模拟,利用秘鲁历史地震事件的合成记录,获得基底隔震建筑在地震动作用下的地震响应。通过这种方式,研究发现,建筑物的最佳固有参数对应于0.20至6.25Hz的近似频率间隔。最后,结果表明,该方法是有效的,可以可靠地应用于结构健康监测系统。

Wavelet Transform Method for the Evaluation of the Seismic Response of One Isolated Building in the Lima Metropolitan Area
Structural health monitoring based on vibration measurements is a process that implements the instrumentation of sensors and methodologies to provide information regarding the condition of a structure, which allows the evaluation of the safety and integrity of structural systems. Because of this, in the past decades, several algorithms have been developed; among them, the wavelet transform is considered an efficient method for the elimination of the error contained in the acceleration recorded by the sensors. However, due to the complex nature of earthquakes and the particularity of the structural systems, the parameters used by the wavelet transform for error elimination in the seismic response are frequently variable. This paper proposes a method to get the seismic response of a base-isolated building subjected to ground-strong motions through numerical simulations of a mathematical model of the structure, using synthetic records based on historical seismic events occurring in Peru. In this way, the research found that the optimal intrinsic parameters of the building correspond to an approximate frequency interval of 0.20 to 6.25 Hz. Finally, the results show that this method is valid and can be reliably applied in structural health monitoring systems.
