规范中风荷载标准值计算公式的各参数解读

风荷载标准值的计算公式几乎在所有结构进行抗风设计时都得到了应用,然而很多工程师并不真正理解公式中各参数的意义和由来,而只是机械地依照规范所提供的附表进行查询.当一些工程师无法查询到附表中相应参数数值时,便束手无策,有甚者胡乱取值,这往往使设计结果不经济或者完全储备过低.文章根据《建筑结构荷载规范》中风荷载部分的规定以及结合近年来一些有关风荷载参数取值的文献和著作,对风荷载标准值计算公式的各参数意义和由来做了简单介绍,以帮助工程师们在实际设计时能更科学地选取参数数值和应用公式.

Interpretation of Each Parameter in Wind Load Standard Value Calculation Formula of Load Code

Wind load standard value formula have been applied in almost all wind-resistant design of structures,but many engineers do not really understand the significance and the origin of various parameters in the formula,only inquire the schedule provided by specification mechanically.When in the face of the status that the appropriate parameter values in the schedule are not available,many engineers are at a loss even randomly valuing,which often lead the design results to be not entirely economic or too low reserve.Based on the provisions of part of wind load in《Load code for the design of building structures》and combined with the Papers and books about wind load parameters＇ selection in recent years.the paper briefly introduces the meaning of the parameters in the wind load standard value calculation formula to help engineers select the parameter values and apply the formula more scientificly in the actual design.
