| 摘 要： | “朝天扬帆”是位于重庆朝天间广场的钢结构雕塑工程,该工程建筑型体复杂、结构布局不规则,通过该雕塑工程缩尺模型的几洞试验,确定其风载计算的体型系数;用时程法计算结构的风振响应,且在模拟作用于结构上的脉动风时程曲线时考虑结构的高度相关性,应用ALGOR93软件对结构进行风振时程分析,并自编程序加以前、后处理。通过对比该结构在脉动风和平均风作用下的杆件内力、节点位移响应,约定结构风振系数,为该雕塑工程抗风设计参数的确定提供理论依据。

| Abstract: | Chao Tian Yang Fan" is a steel structure built in Chaotianmen square of Chongqing. Its architectural appearance is particular and structural arrangement is not uniform. The form coefficient of wind is suggested based on the result of tunnel test of the model. Height pertinence of structure is considered when simulating the time process curve of wind loads. The responses of nodal displacement and internal force of structural members subjected to vibrating wind and average wind are calculated respectively. The wind vibration coefficient is presented by comparing the responses so that the theoretical basement is established for the design parameters of this structure. |
