Abstract :This paper investigates the mechanical characteristics of a combined geometric and material behavior of cylindrical roofs subjected to a concentrated load. The shell elements in the NISA 2016 software are modeled by 3-D general shell element and 3-D composite shell element. The 3-D shell element includes deformation due to membrane, bending, membrane-bending coupling and transverse shear effects and is suited for modeling moderately thin or thick general shells and laminated composite shells. The 3-D composite shell element consists of a number of layers of perfectly bonded orthotropic and anisotropic materials. The objective of this research is to analyze the load deflection curves considering the combined geometric and material nonlinearity of cylindrical shells. The snap-through phenomenon will be investigated for the analytical results of cylindrical shells.
