摘要:

为了明确结构风致振动特性并提出风振系数建议取值,基于风洞试验和数值模拟结果,采用时域法计算了静风荷载和脉动风荷载下不同矢跨比结构的静位移和动力响应; 运用修正的Newmark-β法积分计算得到各节点的时程响应,并采用频域法分析了结构位移响应的频谱特性,得到结构位移响应均方根值,在此基础上计算了不同来流作用下结构各区域的风振系数。结果表明:来流垂直于结构纵向和横向时,结构顶部和尾流区易发生整体大幅涡激共振,斜风向作用下结构顶部和背风区易发生涡激振动; 来流方向对结构各节点位移响应均方根分布特性和其最大值分布影响显著,最大的位移响应均方根为8.5 mm; 特征湍流作用显著的部位风振系数较大,给出的结构各区域在不同来流作用下的风振系数建议取值可供该类结构抗风设计参考。

Abstract:

In order to clarify the wind vibration characteristics of structure and propose recommended values of wind-induced vibration coefficient, based on wind tunnel tests and numerical simulation results, the time-domain method was used to calculate the static displacement and dynamic response of structures with different aspect ratios under static and fluctuating wind loads. The modified Newmark-β method was used to integrate and calculate the time-history response of each node, and the frequency domain method was used to analyze the spectral characteristics of structural displacement response. The root mean square value of structural displacement response was statistically analyzed, and on this basis, the wind vibration coefficients of different regions of structure under different incoming flow conditions were calculated. The results show that when the incoming flow is perpendicular to the longitudinal and transverse directions of structure, the top and wake areas of structure are prone to significant overall vortex-induced resonance, while the top and leeward areas of structure are prone to vortex-induced vibration under oblique wind direction. The direction of incoming flow has a significant impact on the root mean square distribution characteristics and maximum value distribution of displacement responses at each node of structure, with the maximum displacement response having a root mean square of 8.5 mm. The wind vibration coefficient is higher in areas with significant turbulence effects. The recommended values for wind vibration coefficients in different regions of structure under different incoming flow effects can provide reference for wind resistant design of such structures.
