Abstract: Abstract: With the development and application of building membrane materials, there are more and more exhibition buildings with air-supported membrane structure, but the related fire-protection technical standards has not been promulgated. Starting from the concept of air-supported membrane structure and the combustion characteristics of common membrane materials,based on engineering examples, this paper analyzes the fire risk and fire protection design difficulties of air-supported membrane structure, from the aspects of structure, fire?compartment division, personnel evacuation control, interior decoration fire-prevention method, fire water supply, fire detection, smoke control, fire-fighting and rescue method. Then the strengthened fire-protection technical measures of air-supported membrane structure exhibition buildings are explored, and a feasible special fire-protection design scheme is put forward combined with the current fire-protection technical codes and fire simulation results.
