ERIES-Wind Actions By Changing The Ground Roughness

The dataset includes high-resolution velocity measurements of atmospheric boundary layer (ABL) profiles and corresponding surface pressure measurements on a scaled high-rise building model (153 mm × 100 mm × 610 mm in reduced scale). These data were generated through a controlled wind tunnel campaign at a geometrical scale of 1:492 aimed at investigating the effects of uniform and transitional terrain roughness on wind loads. In total, 27 ABL profiles were developed by systematically varying roughness elements to represent Eurocode terrain categories and their transitions. For each ABL profile, surface pressure was measured on an isolated high-rise building model with a rectangular plan to capture the impact of the approach flow on wind loads.<br>In addition to the Metadata report, raw data time series of appraoch flow conditions as well as surface pressures and ambient conditions for the conducted measurements are provided here.本数据集包含缩尺尺寸为153 mm × 100 mm × 610 mm的高层建筑模型上的大气边界层（Atmospheric Boundary Layer，ABL）剖面高分辨率速度测量数据，以及对应的表面风压测量数据。本数据集通过几何缩尺比为1:492的可控风洞试验获取，旨在研究均匀与过渡型地表粗糙度对风荷载的影响。本次试验通过系统性调整粗糙度单元，共生成27组大气边界层剖面，以模拟欧洲规范（Eurocode）中的地表粗糙度类别及其过渡工况。针对每组大气边界层剖面，本数据集通过矩形平面的孤立高层建筑模型采集表面风压数据，以探究来流对风荷载的影响。 除元数据报告外，本次试验所涉及的来流条件、表面风压及环境条件的原始时序数据均已在此提供。
