| Summary |
The double cable-layered membrane structure is one type of newly-developed structure form. It has many advantages such as able to adjust the length of post to discharge water， re-pretensioning of membrane，high damping，etc. In order to grasp the vibration characteristics of this new kind of architectural form，author tried to simulate the vibration of both single cable-layered membrane structure and double cable-layered membrane structure. The emphasis is put on the damping characteristics and the influence of air. From the vibration waves obtained from experiment，using techniques such as Fast Fourier Transformation，the resonance frequency and damping values are obtained. Using the values obtained， author tried to simulate the vibration using modal analysis and non-linear analysis method. The affect of air to vibration is found quite significant as reported in the area of sound vibration subject. Conclusions are made such as the damping effect of double cable-layered membrane structure is greater than that of single cable-layered membrane structure，Raleigh damping can be used to predict the vibration characteristics，added mass of air should be considered，etc.
