Title VIBRATION CHARACTERISTICS OF SUSPENSION MEMBRANE STRUCTURES
Author Norio MASAOKA,Ryo MURANAKA
Summary The present paper specifics fundamental vibration characteristics obtained from experiment on the model of the suspension or the framed membrane structure. The first paragraph describes outline of the free vibration tests on plane quadrilateral and approximate hyperbolic parabolic shaped membrane models. The second paragraph shows influence of vibration amplitude to damping characteristics. SpeciallyEŒit is c1arificd that damping force becomes larger according to larger vibration amplitudeEŒand that damping force of the approximate hyperbolic parabolic membrane model is larger than that of the plane quadrilateral membrane model because of different geometrical configuration. In the last paragraphEŒresults of free vibration analysis on the framed membrane structure which was already completed as a roof of the gymnasium is compared with the experimental results of approximate hyperbolic parabolic shaped membrane models. ConsequentlyEŒfundamental vibration characteristics of the real framed membrane structure is considered to be predicted by assuming stiffness proportional damping or Rayleigh damping.
