Abstract

The wind tunnel test research on the open ring-arched large-span roof, based on the wind tunnel test results, analyzed in the wall under different opening rate of the ring-arched local roof shape factor change rule. The results show that: As the opening rate increases, wind pressure on the outer edge of the roof decreases. When the opening rate is 74% or more, its effect on wind pressure is minimal, with a shape factor difference of around 0.7 between closed and open states. Openings near the outer edge can reduce high negative pressure areas.
