对呼吸式幕墙建筑的结构特点,采用FDS数值模拟对其进行了网格独立性研究,当夹层厚度与夹层方向网格尺寸的比值不少于2.25时,认为其结果满足网格独立性要求。另外,结合了K.Overholt网格计算方法的优点,提出了一种新的解决呼吸式幕墙建筑数值计算的网格计算方法,即R&K网格尺寸计算法。
For the structural characteristics of the breathing curtain wall building, the grid independence was studied by FDS numerical simulation. When the ratio of interlayer thickness and interlayer grid size was not less than 2.25, the result was considered as grid independence. In addition, combined with the advantages of K.Overholt grid computing method, a new grid computing method to solve the numerical calculation of respiratory curtain wall construction is proposed, namely R & K grid size calculation method.
