Topic: Linear Analysis


How can I do a LINEAR analysis? I mean only considering a linear relation in the stress-strain for concrete.

Re: Linear Analysis

Dear neshghi, you do not need ATENA at all for that - use any of the linear design FEM software packages (the one which suits you best). If you wish to use a linear material model for some part of you structure in ATENA, choose the 3D Elastic Isotropic material model, however, please keep in mind that nonlinear geometry is still taken into account, see also ATENA Troubleshooting, 2.1.9 Does the non linear analysis of ATENA consider the geometrical nonlinearity (second order effects, like buckling or necking)?
