Abstract

In this objective paper, an inverted umbrella roof shell are designing and modeling for the static analysis in ANSYS (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. Responses of umbrella roof shell 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 subjected to self-weight or pressure load. These investigations results for laterally loaded inverted umbrella roof shells with analytical and regression analysis on graphs results, by using materials like RCC. The results show that employing less or higher deformation generated in RCC in static analysis with regression analysis and also roof shell is better strength to yield engineering accuracy for design purposes.
