The ‘TRAP - TRuss Analysis Program’ can assist engineers in the analysis of plane truss-type structures, as well asprove an excellent basis for understanding the “finite – element” method. The Program is completely menu-driven, withall nodes, elements, and load data entered through an input file. TRAP includes plotting for displaying the truss geometryin its original shape showing all nodes and support points. In the analysis process, firstly the structure data; e.g numberof nodes, elements, materials and supports are to be defined. Secondly, element properties and support constraints haveto be specified. Finally, nodal global loads are then defined. The program output include; displacements for each node,axial forces, length of each element and reactions at the supports.The program aims at reducing the time of analysis and increase the accuracy of calculations as well as storage of theanalysed data. The program caters for manual methods of truss analysis such as method of sections or joint method. Ithas been found that the program is efficient and has no limitations on the number of nodes and elements. The program is suitable for use by design engineers in analysing Plane – Trusses of any size.
