Membrane structure stands an important building material in modern buildings. It has stable performance, good toughness, convenient processing and production, is suitable for mass production, and is easy to control quality and fast installation. It is a combination of performance, beauty and environmental protection. Can a beautiful and beautiful membrane structure building resist the typhoon?
The problems of compression resistance, earthquake resistance and typhoon resistance of membrane structure buildings are the problems to be solved in the early stage of design. From the practical point of view, if the design is based on the magnitude of earthquake resistance, constant live load, wind load, etc., it needs to meet the requirements of the standard. Because the membrane structure is a wind-sensitive structure, there is the problem of aerodynamic instability. Essentially, the structural air instability is due to the structure absorbing energy during the vibration and the mode coupling of the airflow. When the absorbed energy is greater than the dissipated energy, energy accumulation will occur. When this energy accumulation reaches a certain level After the value of, the structure will change from a low-energy vibration form to a high-energy vibration form, so the wind load will be determined according to the actual environment, the size of the windward surface, and the slope of the surface, and the constant activity will be determined according to actual needs. The design of the membrane structure that starts after the load size must ensure that a stable three-dimensional balanced surface with uniform stress distribution is generated, and it can withstand various possible load conditions, wind, compression, and earthquake. And to ensure its safety.
