摘　　要：附着式升降脚手架在高空作业时主要承受风载荷,实际中风载荷是十分复杂的动函数。为了提升附着式升降脚手架在高空工作时的安全性设计水平,以河北唐山某地升至60 m高空作业时的附着式升降脚手架为研究对象,根据Davenport风谱在MATLAB中模拟了60 m高空的脉动风载荷,将模拟的风载荷值导入ANSYS对脚手架进行了脉动风致响应分析,得到在200 s脉动风激励时程内脚手架的顺风向最大位移为11.651 mm,该方法及分析结果对于工程中抗风设计具有很大的参考价值。Attached lifting scaffolding mainly bears wind load when working at high altitude,and the actual wind load is a very complex dynamic function.In order to improve the safety design level of attached lifting scaffolding when working at high altitude,the attached lifting scaffolding working at an altitude of 60m in Tangshan,Hebei Province is taken as the research object.The fluctuating wind load at 60m altitude is simulated in MATLAB according to Davenport wind spectrum.The simulated wind load value is introduced into ANSYS to analyze the fluctuating wind-induced response of scaffolding.The maximum radial displacement of scaffolding during 200s pulsating wind excitation is 11.651mm.The method and the analysis results are of great reference value for wind resistance design in engineering.
