摘要

摘要:以内蒙古乌海市奥林匹克中心体育场为工程背景,进行了刚性模型同步测压风洞试验,研究了2个不同高度挑篷之间的相互干扰效应,包括总风吸力、平均和脉动风压系数分布、以及典型测点的风压功率谱等。结果表明:高挑篷对低挑篷风荷载的干扰在某些风向角下较大,且主要表现为“遮挡”效应;低挑篷对高挑篷的干扰也主要表现为“遮挡”效应,但小于高挑篷对低挑篷的影响。

Abstract

Summary: Taking the stadium of Mongol Wuhai Olympic center as project background, by adopting wind tunnel test with synchronously measured pressure on the rigidity model, we have studied the interference effects between two coverings with different altitude, including total wind suction, the distribution of average and fluctuating wind pressure coefficients, and the wind pressure power spectrum of main test points, etc. The results manifest that the interference of the higher canopy roof to the lower is significant on some angles, and it mainly affect as ‘cover effect’; The interference of lower canopy roof to the higher is the same, but not as obviously as the effect that the interference of the higher canopy roof to the lower .
