Influence lines constructed using Autodesk Robot

Influence functions and their graphical representation – influence lines are used in calculation of structures exposed to moving loads. They are used to determine the position of the moving load that will give the most adverse impacts of construction or its components (maximum internal forces, deflections and displacements), and to determine the values of these quantities. The aim of this work is to analyse influence lines of statically determined and indetermined systems obtained by software, and compare them with the same obtained by analytic methods. In recent years, computers have become an indispensable tool to every engineer in practice, and it is necessary to accepted numerical results obtained by various applications with exceptional caution, and also study the possible limitations of some software. A few examples of statically determined and indetermined systems are studied influence lines obtained software package Autodesk Robot Structural Analysis and observed a good correlation with the analytical results. The resulting operating errors can be generalized and corrected by the input parameters of the program, so the results can be used for static analysis of structures.
