Over recent years, rigid porous plates with higher wind resistance coefficients have become more frequent in construction projects, replacing flexible dense mesh safety nets. This change has resulted in a substantial increase in the load on the surface of the clad scaffolding. The paper is centered on the characteristics of wind load on the cantilever construction scaffolding of a high-rise building in Xi’an, with the objective of concluding the distribution rules by field measurement. The study revealed that the non-Gaussian characteristics of wind pressure are most pronounced near the incoming separation point and the middle of the building surface. The local wind force coefficient adheres to a logarithmic distribution pattern with the wind pressure turbulence. The turbulence, gust factor, and skewness and kurtosis of fluctuating wind pressure exhibit an “S-like” distribution along the building surface. Based on the research findings, as the wind pressure increases significantly, two correlations between the mean value of the fluctuating stress and fluctuating wind pressure were identified: linear and mean fluctuation.

基于现场实测的高层建筑悬臂式脚手架风荷载特性研究


近年来，具有较高风阻系数的刚性多孔板在建筑项目中越来越常见，取代了柔性密网安全网。这种变化导致堆焊脚手架表面的负载大幅增加。本文以习安某高层建筑悬臂式施工脚手架上的风荷载特性为中心，旨在通过现场测量得出分布规律。研究表明，风压的非高斯特性在入射分离点附近和建筑物表面的中间最为明显。局部风力系数服从风压湍流的对数分布模式。湍流、阵风因子以及波动风压的偏度和峰度沿建筑物表面呈现“S 状”分布。根据研究结果，随着风压的显著增加，确定了波动应力平均值与波动风压之间的两个相关性：线性和平均波动。
