随着国内气膜体育馆建设地越来越多，社会对气膜建筑的安全性的广泛关注。大家觉得气膜体育馆就像一个大型的充气气球，十分脆弱。有人开始担心气膜建筑到底安全不安全？
有事故≠膜结构易坍塌
通常有三种情况造成气膜建筑坍塌：一是存在设计缺陷；二是膜材料质量不过关，比如拉伸强度不够；三是施工或维护不当。只要严格遵循相关规范设计、制作、安装和运维，膜结构馆的安全性就可以得到保证。
气膜建筑技术起源于国外，从上世纪60年代开始进入民用领域。经过半个世纪的发展，欧美国家已形成从设计、制作、安装到运维的一整套气膜建筑行业规范：什么等级的膜材料适用于什么用途，不同气候条件下建筑物的位置和朝向该如何设计等，都有非常具体的要求。正是由于有完善的行业规范，国外较少发生气膜建筑破裂、坍塌事故。
即使从发生事故的角度而言，气膜建筑的安全系数也要高于传统钢混结构场馆。无论哪种情况造成了气膜建筑坍塌，其降落速度都较慢，气膜建筑从开始坍塌到完全坍塌，至少会有30分钟的时间，在气膜建筑内的人员有充足的撤离时间，且膜结构自重较轻，内部人员需要承受的重量也小于钢混结构。

What maintenance is needed for an air membrane basketball hall after construction?
A: An air-supported basketball gym is a type of air-supported building and air-supported sports facility. It maintains a constant temperature and humidity year-round, and features many advantages such as light weight, large span, fast construc...
Mr. Wang:
Overview of air membrane buildings
A: Air membrane buildings are far less long-standing than traditional buildings in terms of development history, but they are a great progress of human civilization. People are still unfamiliar with air membrane buildings, so what are air memb...
Mr. Ren:
What are the advantages of air membrane buildings?
A: The internal space has no beams or columns, which can effectively improve the utilization rate of the original building; the membrane material has the functions of windproof, snowproof, haze-proof, fireproof, shockproof, etc.; low cost, sho...
Mr. Yu:
Are air membrane buildings safe? What about fire protection design?
A: The roof load-bearing components of air membrane buildings are fire-retardant materials, and the fire resistance rating of the project is determined as Grade III, which is equivalent to the brick-wood structure composed of wooden roof and b...
A: Small damage to the air membrane structure building will not affect the safety of the building itself, and timely repair can solve the problem. If a large hole (with an area of more than 1 square meter) is punctured, the air pressure inside...
Mr. Dong:
Approval and construction procedures for air membrane buildings in China
A: The approval procedure for air membrane buildings is relatively simple, and the submission and approval are carried out according to the nature of temporary buildings. According to the policy differences in each region, the approval and fil...
