| Summary |
A membrane structure is required the initial tension in its membrane surface to be stabilized by itself. To analyze such a structure by the finite element method. the geometrical nonlinearly should be considered. Generally. long period of computation is required for a static or a dynamic nonlinear analysis considering the stress concentration and the wrinkling due to its material characteristics. Thus. an efficient computation is one of the important matters.
In the present paper. to improve the computation efficiency. the membrane structure is analyzed with a bilinear quadrilateral element with one-point quadrature based on the reduced integration technique already used in the plate and shell structure analysis.
Based on the results obtained through the form finding analyses. it is investigated a feature of the present element and the computation efficiency
