| Summary |
The double cable-layered membrane structure is one type of newly-developed structure form and is quite unknown about its dynamic characteristics. Following model experiment，the author tries to have a general grasp of the dynamic characteristics of double cable-layered membrane structure by analysis of full-sized experiment result of Osaka Pool. First， the resonance frequencies are obtained using techniques such as Fast Fourier Transformation. Then damping values are decided from vibration waves obtained from experiment. By eigenvalue analysis ，the author got mode shapes ，resonance sphere of Osaka Pool and discussed the possibility of resonance with wind. The double cable-layered membrane structure is consisted of high-stiffness down layered cable-net and low-stiffness upper-layered membrane， it is considered to act specially compared to ordinary single-layered structure. Utilizing partial structural division method，the special vibration behavior is grasped numerically. At last，the connection between model experiment and full-size experiment is discuss
