A Novel Structural Analysis Program by Stiffness Method for Analysis of Trusses

Azhar Uddin, Sumit Pahwa

Abstract: Structural analysis is the backbone of any engineering design by letting one knows ahead of time the behavior of any engineering structure under different loading conditions to which structure will come across throughout its life. This report demonstrates how a structure could be defined and analyzed using the program named structural analysis by stiffness method (SABSM). Moreover how a user can use this program as a learning tool for direct stiffness method specifically by going through each step of the solution reported back by the SABSM. SABSM is developed for static elastic structural analysis of 2D and 3D pin and rigid jointed frames and a learning tool for direct stiffness method. Structure could have any geometry and different end conditions.
