膜结构的基本功能是安全可靠地连接膜部件。经过近几年的发展，膜结构节点设计不仅实现了其基本的结构功能，而且满足了建筑美学的要求。
1.1传力路径短，内力传递有效。负高斯双曲面是张拉膜结构稳定的必要条件。接缝设计必须能够将复杂的膜表面和膜角力转移到膜结构的其他部分，并确保与膜表面形状协调。
1.2足够的强度，
节点的稳定性、耐久性和良好的力学性能是保证膜结构整体性能的重要因素。接头设计必须考虑可能的局部应力集中和接头处的膜材料弱化引起的接头性能。
1.3必要变形协调膜结构是典型的大变形结构。在膜结构设计的各个阶段，都必须考虑其大变形特性。在精确设计节点的基础上，还应允许一定量的位移和旋转。同时
接缝设计中必须考虑深圳膜材的预张拉和二次张拉。
1.4建筑外观的完整性
膜结构强大的建筑表现力是其重要优势之一。在满足力学性能的基础上，连接节点应尽可能与膜结构的整体几何形状和建筑外观相一致。
Ms. Liao:
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...
