Nonlinear analysis of structures

Nonlinear analysis

The LIRA-FEM (LIRA-SAPR) software provides a nonlinear solver to analysis of nonlinear problems.

The nonlinear solver is mentioned to solve physically and geometrically nonlinear problems, as well as problems with structural nonlinearity and prestressing.

Nonlinearity in LIRA-FEM program

In LIRA-FEM program, it is possible to take into account the following types of nonlinear behaviour of structures:

Physical nonlinearity
Geometric nonlinearity (P-delta)
Structural nonlinearity
Genetic nonlinearity
Engineering nonlinearity

Analysis of RC beam with account of physical nonlinearity

The procedure for setting the properties of physical nonlinearity for materials with account of the creep in concrete and the procedure for setting the parameters of reinforcement; generation of a table for modelling nonlinear loads.
