Equivalent Shell Model of Elastic Gridshells Including the Effect of the Geometric Curvature

In this work, an equivalent continuum of a barrel gridshell is introduced. Constitutive identification procedures based on periodic homogenization are provided in the literature for purpose, flat Representative Element Volume (REV), notwithstanding that geometry structures concerned curved. Therefore, novelty present study selection curved REV to obtain elastic constants. The numerical validation procedure made comparing response shell under homogeneous load conditions. Finally, order highlight effect constitutive law continuum, proposed model also compared obtained from REV.
