摘　　要：基本风速或风压、高度影响系数、风振影响系数(阵风影响系数)及体形系数是影响石化装置中开敞式钢框架风荷载计算的重要因素。通过对美国《石油化工和其他工业设施的风荷载导则》及中国《建筑结构荷载规范》中关于开敞式钢框架风荷载计算方法和影响因素进行对比分析,为石化装置中开敞式钢框架风荷载计算方法提供一定的参考。Basic wind speed or wind pressure,velocity pressure exposure coefficient,gust effect factor and shape coefficient are the most important factors that affect the wind load calculation for open steel frame structures in petrochemical plant. By comparing the wind load calculation methods and the influencing factors for open steel frame structures between the Wind Loads for Petrochemical and Other Industrial Facilities published by the ASCE Petrochemical Energy Committee and the Chinese standard Load Code for the Design of Building Structures,this article provides some references for the wind load calculation of open steel frame structures in petrochemical plant.
