In this paper, analysis of reinforced concrete cylindrical shells is performed using a strain-based finite element. The shell element employed is bidimensional, cylindrical circular and has four nodes and five nodal degrees of freedom. The nonlinearities due to concrete cracking and yielding and yielding of the steel are taken into account. The constitutive models for the materials employ the smeared cracking concept and a finite element layered approach. Concrete is modeled by a strain-induced orthotropic-elastic model under plane state of stress. A bilinear steel model is used and the stress reversal with Baushinger effect is included. Examples show the good accuracy provided by this analysis.
