北京某国际金融大厦风荷载与火灾流场的数值模拟

对北京金融大厦风荷载进行了计算机数值模拟，给出院 风洞中模型表面风荷载随风向角变化的一般规律并和文献1]的实验结果进行了比较。给出了实验模型周围的流动图画和气流参数的分布规律，另外，分析了构成该建筑的四栋相邻近的建筑之间发生火灾后的流动特性，提出了比其它建筑结构更易于扩大火灾发展的原因和补救措施。

Numerical simulation on the wind action and fire-induced flow field of an international finance building in Beijing

Wind action on the four connected buildings of an international fi nance building in Beijing was simulated. Variations of the wind pressure data on the buildings with the wind direction were presented and compared with the wind tunnel results measured in the literature. Pressure contours and velocity vecto rs around the buildings were predicted. Analysis of the distribution of temperat ure and velocity between the four buildings showed that a fire plume can be deve loped rapidly. Better design for providing fire safety was recommended.
