基于高阶振动模型的建筑抗震性能检测

Seismic Performance of Buildings Detection Based on High-Order Vibration Model

建筑物的抗震能力一直是建筑学领域研究的热点问题之一。传统的建筑震动检测方法都是已建立的建筑物的抗震信号模型,但是外界振动信号的突变性较大,从而降低建筑振动信号模型检测的精度。提出一种以无线传感振动信号为基础,配合高阶振动模型设计的建筑物抗震性能检测技术,准确的设计传感器对突变信号的检测规律,可以防止控制溢出被有效抑制,运用抗震控制律对抗震性能进行检测。仿真结果表明:该方法对突变信号较强的建筑振动模态进行抗震性检测,对检查中的干扰有着较好的抑制,提高了检测的准确度。

This paper puts forward a wireless sensor to vibration signal as the foundation, with a high order vibration model design of the building aseismic performance testing technology, accurate design sensors to mutation signal detection rules, can prevent control overtlow is effectively controlled, using seismic control law to aseismatic performance testing. The simulation results show that the method of mutation signal strong building vibration modal for earthquake-resistance testing, check the interference has good inhibition, improve the detection accuracy.
