Abstract

This paper presents a full-scale monitoring system installed on a 50 m tall telecommunication lattice tower located in Sânnicolau Mare, Romania. The system has the dual purpose of measuring wind velocity and the wind-induced response of the tower, with particular attention to thunderstorms. It includes an ultrasonic anemometer, a temperature sensor, two triaxial accelerometers, six strain gauges and a video camera system. A first set of data recorded between January 2021 and December 2022 is analyzed in order to compare the dominant properties of thunderstorm and synoptic wind records and reveal the corresponding structural response. An improved approach to wind characterization based on anemometric and video data is proposed to separate the wind records into depressions and thunderstorms, highlighting the innovative use of video sequence to support classification of events. Anemometric and video data related to detected depressions and thunderstorms are presented, together with their full statistical characterizations. Wind induced structural response due to depression and thunderstorm records are described in terms of acceleration and strain. Patterns of depression and thunderstorm-induced response are presented, with the aim of emphasizing their diversity and complementing the identification of thunderstorms. Correlation of simultaneous wind velocity and structural response records is finally analyzed.

在天气和雷暴风下对电信格塔的全面监测

本文介绍了一种安装在罗马尼亚s尼尼科劳海50米高的电信格塔上的全尺寸监控系统。该系统具有测量风速和塔的风致响应的双重目的，特别注意雷暴。它包括一个超声波风速计，一个温度传感器，两个三轴加速度计，六个应变计和一个视频摄像系统。分析了2021年1月至2022年12月记录的第一组数据，以比较雷暴和天气风记录的主要特征，并揭示相应的结构响应。提出了一种改进的基于风速和视频数据的风特征描述方法，将风记录分为低气压和雷暴，突出了视频序列的创新使用，以支持事件分类。介绍了与探测到的低气压和雷暴有关的风速和视频数据，以及它们的完整统计特征。由低气压和雷暴记录引起的风致结构响应用加速度和应变来描述。提出了低气压和雷暴诱发响应的模式，目的是强调它们的多样性，并补充雷暴的识别。最后分析了同时风速与结构响应记录的相关性。

期刊介绍： The objective of the journal is to provide a means for the publication and interchange of information, on an international basis, on all those aspects of wind engineering that are included in the activities of the International Association for Wind Engineering http://www.iawe.org/. These are: social and economic impact of wind effects; wind characteristics and structure, local wind environments, wind loads and structural response, diffusion, pollutant dispersion and matter transport, wind effects on building heat loss and ventilation, wind effects on transport systems, aerodynamic aspects of wind energy generation, and codification of wind effects. Papers on these subjects describing full-scale measurements, wind-tunnel simulation studies, computational or theoretical methods are published, as well as papers dealing with the development of techniques and apparatus for wind engineering experiments.
