【摘要】：本文首先介绍了工程结构动力性能检测技术的新发展，国内外研究现状，，现有的技术成果，本人课题的研究目的、方法、内容及意义等，然后结合我们的实践研究，参考现有的技术成果及相关的技术规程、规范、法规等详尽介绍了动力检测的适用范围，检测仪器的技术参数要求，检测步骤、方法，检测方案的制定，实时数据的保存与整理，动力性能检测的评价体系等，最后通过若干工程案例展示了研究成果的可靠性与前瞻性。论文就建筑结构动力性能检测技术与评价的核心内容提出了有见地的成果，其中包括：采集器的工作原理、测点布置方法、采集器的校核以及检测实施工程中的注意事项，特别制作了检测方案实施表格；检测适用范围的定性认定与论证；受到周围环境、信号传输等不确定因素影响的检测数据预处理；高层建筑结构与大跨空间结构模态参数差异识别等。这些都为动力性能检测技术的发展提供了有力参考。当然，笔者也认识到该项技术的发展还存在诸多问题。如动力性能检测的对象还需进一步论证；采集器的计量标定需设定标准；采集器布置如何优化；采集数据的有效性如何评价；损伤识别的综合分析等。但考虑到其特殊的优点、低廉的成本，相信随着该体系的完善，与现行静力检测技术相结合必将为工程结构可靠性鉴定提供强大武器。
[Abstract]:This paper first introduces the new development of engineering structure dynamic performance testing technology, the domestic and foreign research status, existing technical achievements, my research objectives, methods, content and significance. Then combined with our practical research, referring to the existing technical achievements and related technical procedures, norms, regulations and other detailed introduction of the scope of application of dynamic testing, the technical parameters of testing equipment requirements, testing steps. Methods: the design of testing scheme, the preservation and arrangement of real-time data, the evaluation system of dynamic performance testing, etc. Finally, the reliability and foresight of the research results are demonstrated through several engineering cases. In this paper, the core contents of dynamic performance testing and evaluation of building structures are presented, including the working principle of the collector and the layout of measuring points. The checking of the collector and the matters needing attention in the detection and implementation project, especially the implementation form of the test scheme is made. The qualitative identification and demonstration of the scope of application; Pre-processing of detection data affected by uncertain factors such as surrounding environment, signal transmission and so on; The difference identification of modal parameters between tall building structures and long-span spatial structures provides a powerful reference for the development of dynamic performance testing technology. Of course, the author also recognizes that there are still many problems in the development of the technology, such as the object of dynamic performance testing needs further demonstration; The measurement and calibration of the collector need to set the standard; How to optimize the arrangement of the collector; How to evaluate the validity of data collection; In view of its special advantages and low cost, it is believed that with the improvement of the system, the combination of this system with the current static detection technology will provide a powerful weapon for the reliability evaluation of engineering structures.
