摘要

The analysis of wind load characteristics of gas-ribbed film structure plays an important role in the performance of the long-span membrane structure.This paper mainly researches on the long-span rib membrane structure.Surface wind pressure of the membrane structure is calculated by fluent,the distribution of force and surface pressure of the membrane structure under different angles and wind speeds is obtained.The worst working condition of the wind approach angle is 60°.Maximum force angle is positively correlated with windward angle and the length of structure.
