NLframe2D is an application to perform geometrically nonlinear static analysis of two-dimensional frame models.
The program considers Euler-Bernoulli theory for bending behavior of beam elements, rigid connections between elements and concentrated nodal loads.
Users can select between several formulations and solution options to perform the numerical analysis.
This program was conceived as an auxiliary tool for the MSc thesis "Educational Tool for Structural Analysis of Plane Frame Models with Geometric Nonlinearity":

A new version of this program (now called NUMA-TF) with more analysis options is available:
