Title DYNAMIC ANALYSIS OF MEMBRANE STRUCTURES IN CONSIDERATION OF WRINKLING
Author Junichi FUJII
Summary Membrane structures have many special problems from their special structural characteristics. One problem is that geometrical nonlinearity should be considered in the static and dynamic analysis because large deformation is generated from their flexible characteristics. The other problem is that wrinkling occurs occasionally because membrane elements can not transmit compressive forces. In this paper, the nonlinear dynamic analysis of suspension membrane structures is conducted in consideration of these two problems. The Newmark.╬▓method is applied for the time integration. As a results, the basic characteristics of the vibration and the effects of the wrinkling phenomena on the vibration have been grasped.
