Study on the Key Technology of Membrane Roof Structure of Expo Axis in 2010 Shanghai World Expo

摘要：

　　The large scale cable-membrane structure is widely used in the Expo Axis.The structure iscomposed of continuous triangle shaped membrane unit.The representative local part of membranestructure is selected to carry out double-layer membrane strength experiment and reduced-scaleexperiment to test its mechanical per formance and strength index during tension.The results show thatthe bearing capacity of double-layer mem brane structure is more than 1.8 times of single-layermembrane; Material strength and joint strength are all in agreement with the design.Through theanalysis of membrane shape decision and membrane processing key technology, it can be concludedthat form-finding must be considered in membrane self-weight, and the reinforcement membrane andontology membrane should be at the same direction.
