中文摘要：
在基于小波包能量谱的结构损伤预警方法基础上，开展了Benchmark结构损伤预警的试验研究。通过Benchmark试验模型模拟结构的多种损伤状态，并采集模型在结构损伤前后的动力响应，在此基础上计算了结构损伤预警的小波包能量谱及其损伤预警指标。试验结果表明：基于小波包能量谱的结构损伤预警指标具有良好的损伤预警能力，可以准确地判定结构初期损伤的发生。
英文摘要：
The experimental research on structural damage alarming of Benchmark structure is performed in this paper based on the structural damage alarming method using wavelet packet energy spectrum. Various damage statuses are simulated through the Benchmark test model, and thus structural dynamic responses are collected with respect to the intact model and damaged models. Based on the collected structural responses, the wavelet packet energy spectrum and corresponding damage alarming indices are calculated. Experimental results reveal that the structural damage alarming indices calculated by the wavelet packet energy spectrum have preferable damage alarming capacity and can effectively detect the structural initial damage.
