How strong is the wind and snow resistance of the general membrane structure stands?
3. Dynamic analysis of wind vibration Wind power can be divided into two parts: average wind and pulsating wind. The average wind period is long, and the general properties of low structure are equivalent to those of decision makers. The period of pulsating wind is relatively short, and the overall use of the structure is dynamic. 4. The aerodynamic instability membrane structure is a wind-sensitive structure, which has the problem of aerodynamic instability. The aeroelastic instability of the structure is essentially due to the energy absorption of the structure during vibration and the modal coupling of airflow. When the absorbed energy is greater than the dissipated energy, energy accumulation will occur. When this energy accumulation reaches a certain value, the structure will change from low-energy vibration form to high-energy vibration form.
