| 摘 要： | 城市风易损结构在台风等强风灾害下的损坏及倒塌将严重影响城市社会的运行安全。以户外广告牌作为典型城市风易损结构物,提出基于结构参数的风易损结构抗风分析方法。针对城市广告牌分布具有的区域空间分布特征及局部风效应,以城市区域风灾为研究对象,结合区域数值风场模拟分析对城市区域风灾损失进行了分析研究。

| Abstract: | The damage of Wind vulnerable structures in urban area will lead to heavy losses and influent society safety.In this paper,the outdoor advertising board is studied as typical Wind vulnerable structure and an analysis method based on basic structural parameters is presented.Considering the space distribution of outdoor advertising boards and the local wind effect,the Wind damage loss for the urban regional area is investigated with the simulation of numerical wind field. |
