The numerical investigation shows that the fundamental period of tall steel structure and the basic wind pressure have no influence on the TMDs optimum design parameters. 数值研究表明:高层钢结构的基本周期和基本风压不影响TMDs最优设计参数;
Based on the achievement about wind damage losses and utilizing calculation method of towering structures and applying fundamental theory of wind engineering, this paper inferred a calculation method of wind pressure in elastic limit which is the vital value in forecasting wind damage losses of tower structures. 根据已有的有关风灾经济损失预测的成果,针对高耸结构中的烟囱类结构,应用风工程计算基本理论,导出了风灾经济损失预测中的关键值&弹性极限风压,可供设计应用。
Fundamental wind pressure is the basic data in structural wind resistance design, the fundamental wind pressure provided by the Building Loading Code is obtained under the "standard conditions". The actual building's site condition is not coincides with the "standard conditions" commonly. 3基本风压是工程结构抗风设计中必须具有的基本数据,荷载规范提供的基本风压是在标准地貌下得到的,而实际建筑地点一般都不满足标准条件。
Fuzzy determination of actual fundamental wind pressure during structural design of building 建筑结构设计中实际基本风压的模糊确定
