Main features and characteristics

The main features and characteristics of the program are the following:

• Reads model from a text file
• Has a basic interface for drawing the model
• Calculates nodal displacements, element forces and constraint reactions
• Exports the analysis results in txt format
• Supports only nodal loads (no elemental loads)
• Supports hinges (rotational releases) at the elements' ends
• Very good documentation within the source code, as it was mainly created for teaching purposes

Program for the Linear Static Analysis of Space (3D) Trusses with Matlab, v1.00, 4 January 2016
(c) Copyright 2016, Vagelis Plevris and George Papazafeiropoulos

Main features and characteristics

The main features and characteristics of the program are the following:

• The 3D model is described in an input file (in text format).
• The program draws and shows the model in a simple figure (in 3D). The user can rotate the figure and view the 3D model in different angles.
• It calculates the Node Displacements, Element Forces, Stresses and Strains and the Constraint Reactions.
• The results of the analysis are written in an output file (in text format).
• It supports nodal forces, given in the global coordinate system (Fx, Fy, Fz).
• The source code is well commented, since it is developed mainly for educational purposes.
• The results of the program have been verified by comparison with the results of ABAQUS (v 6.13.1) and SAP2000 (v 17.2.0) software (see “Verification files”).
