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

PTrussMatlab v1.00

Program for the Linear Static Analysis of Plane Trusses with Matlab, v1.00, 1 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 model is described in an input file (in text format).
  • The program draws and shows the model in a simple figure.
  • 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).
  • The source code is well commented, since it is developed mainly for educational purposes.

STrussMatlab v1.00

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”).
