Author Norio MASAOKA,Kazuo ISHII
Summary The membrane structure„ÄÄwhich has complicate curved surface expends long computation time for prediction of its dynamic nonlinear behavior. ThereforeĀEĆit is important to find the effective element for computation efficiency and accuracy. At the stress deformation analysis of membrane structuresĀEĆthe present paper represents feature of quadrilateral membrane elementĀEĆa bilinear quadrilateral membrane element with one-point quadrature based on the reduced integration techniqueĀEĆwhich is expected to have higher computation efficiency. Specially the present paper shows outline of formulation of this element and determination of its analytical algorithm by the tension field analysis. And also this element is compared and discussed with the constant strain triangular elementĀEĆor the bilinear quadrilateral element with the normal quadrature through the several numerical analyses.
