Abstract: In this objective paper a inverted umbrella roof shell and all sides fixed rectangular plate are designing and modeling for the static analysis in ANSYS Workbench (15) using finite element method. The finite element analysis is carried by using total deformation and normal stresses in longitudinal direction and on X and Y plane to determine respectively. Response of umbrella roof shell as well as rectangular plate subjected to uniformly distributed loads. Both results are linear and quadratic variation of the membrane displacements in the inverted direction are investigated and it is the found out by the quadratic variation is far superior. The effect of the large deformations is incorporated in that the present static analysis by including the first order normal stresses on X and Y plane. This present work material behavior is assumed to be isotropic elastic-plastic. Analytical investigations of the method are carried out by modeling and designing inverted umbrella roof shell and rectangular plate subjected to self weight or pressure load. These investigations compare the results for laterally loaded inverted umbrella roof shells with fixed all sides of rectangular plate with analytical and regression analysis on graphs results, by using two different materials like RCC and Ferrocement. The results how that employing less deformation generated in ferrocement as compared to RCC and also roof shell is better strength as compared to plate roof to yield engineering accuracy for design purposes.
