PAENN2 is a plane frame structural analysis tool, based on the direct stiffness method. This is version 2, which is a port of the original program to C#/WPF.

PAENN

PAENN is a structural analysis tool, capable of determining and displaying the internal forces and displacements of any input structure.

Features

In its current version, PAENN supports:

• Static analysis of plane frame structures, being able to determine the internal forces and displacements on every point and displaying them via internal force and deformation diagrams;
• Allows for placement of concentrated forces/moments, distributed (constant and linear) loads, thermal gradients, support displacements, and nodal liberations (hinges);
• Being built on WPF (C#), the program boasts a friendly, interactive user interface: users can create structures with a few clicks, and readily have the results shown.
