钢结构不可避免发生的缺陷、损伤和老化及施工中产生的工程事故都要求对损伤进行定位、定量的检测。小波空间分析技术的频域——空间域局部特性为大跨空间钢结构损伤定位提供了新的思路和方法。在环境荷载作用下,弦支穹顶结构仿真模型试验结果证实了该方法的准确性和可靠性,表明了该方法的简易性和实用性。
Steel structures inevitable defects, damage and aging and engineering accidents arising from the construction require positioning and quantitative testing of the damage. The local characteristics of the frequency-space domain of the wavelet spatial analysis technology provide a new way of thinking for the damage localization of the steel structure in the long-span space. Under the action of environmental load, the simulation results of the test of the suspen-dome confirm the accuracy and reliability of the method, which shows the simplicity and practicability of the method.
