对于屋顶为双曲抛物面的建筑,主要国际标准中没有计算其风荷载的参数数据。然而,这种类型的屋顶比传统结构更有优势,且特别适用于中等跨度和大跨度结构中。研究旨在参数化4种不同形状(分别为正方形、长方形、圆形和椭圆形)双曲抛物面屋顶的风压系数。特别针对椭圆形屋顶进行了研究。为计算压力系数,对不同形状的屋顶进行了空气动力学风洞试验,并将椭圆形与圆形屋顶进行了对比,证实了椭圆形屋顶的高效性。
For buildings with a hyperbolic parabolic roof, there is no parametric data for calculating wind loads in the major international standards. However, this type of roof is more advantageous than conventional structures and is particularly suitable for medium-span and long-span structures. The objective of the study was to parameterize the wind pressure coefficient for the hyperbolic parabolic roofs of four different shapes (squares, rectangles, circles and ovals, respectively). In particular, the oval roof has been studied. In order to calculate the pressure coefficient, aerodynamic wind tunnel tests were conducted on different shaped roofs, and the ellipse and the circular roof were compared to verify the high efficiency of the oval roof.
