Research on Wind Load Characteristics and Wind-induced Responses of the Opening Roof Structure for Stadiums
摘要
以深圳石岩大树林公园开敞式体育场为例
进行开敞式屋盖结构风荷载特性、结构自振特性、风振响应特性、风振系数研究。首先
通过风洞试验
给出了24个不同方向角结构表面的风荷载分布
挑选较为不利的风向角。其次
进行了结构自振特性研究
分析了结构的刚度薄弱处和振动特点。然后
在对结构表面风荷载分析的基础上
选择6个典型的风向角进行结构的风致动力响应分析。最后
对动力分析结果进行统计分析
提出了可供设计参考的风振系数建议值
为今后工程人员设计开敞式屋盖结构提供参考。
Abstract
The paper
which takes the opening roof structure for stadiums as an example
is to conduct a systematic study on the wind load characteristics、vibration modes of the opening roof structure、wind-induced response of opening roof structure、and gust response coefficients.At first
the wind loads in 24 different wind directions were given
which were derived from the wind tunnel tests
and the unfavorable wind direction is selected.Then
the natural vibration characteristic of the structure was studied
and the vibration characteristics were analyzed.After that
on the basis of the analysis of wind loads on the surface of the structure
6 typical wind directions were selected to analyze the wind-induced dynamic responses of structure.Finally
the paper performs a statistical analysis of the wind-induced responses and proposes the suggested values of the wind-induced response and gust response coefficients of structure
which is provided to designers as references for the wind load-resisting of similar opening roofs.
