| Summary |
We have shown examples of a cutting pattern analysis and a dynamic analysis using the finite element technique of which an unknown quantity is the coordinate value on a stability form. This procedure can examine the mechanical behavior of the tension structure in the 3 dimensional space based on the state of the tension material (membrane and cable) that exists on the plane. In this paper, the example of the dynamic analysis on the tension structure (hybrid structure) to take the beam element to this finite element technique is shown. The beam element cannot do the discretization formulation by the finite element technique with coordinates assumption usually. However, it is shown that it is possible by a simple contrivance. The decision of the cutting line obtains the model of a detailed element breakdown by starting from a comparatively rough element breakdown, and repeating the cutting pattern analysis. The dynamic analysis model is a hybrid structure with a mass suspended by wires, using the obtained element breakdown. The dynamic external forces use the fluctuating wind velocity data.
