Typically, a (cold formed) metal truss would take 3 1/2 to 4 hours to design using conventional structural engineering software. RS3 is a 3D finite element analysis program that can be used for a wide range of applications in both rock and soil, such as. This easy to use program will save you time and money in the analysis, design and estimating of light-gauge (cold formed) metal trusses.

Download structural analysis software 2D Truss Analysis 2.0 developed by EngiSSol. GRASP is a 2D structure analysis software. 2D Truss Analysis is a powerfull application which uses optimized finite elements (bar elements) in order to perform static analysis of trusses. GRASP Stands for Graphical Rapid Analysis of Structures Program. The software can also be downloaded for use on student computers.
In this article, we will study these methods and discuss some additional essential points that need to be considered for the analysis of a truss.
Draw polygons for all joints (4), starting with known loads or bars (for symmetrical trusses half analysis is needed).Graphical Rapid Analysis of Structures Program (GRASP) The software is available at the Open Access Labs (OAL) and the Virtual OAL at in Programs under the Windows Start menu. The analysis of truss can be done by several methods, but the two most common methods of analysis of determinate trusses are the method of joints and the method of section. G Draw equilibrium arrows on opposite bar ends then proceed to the next joint with two unknown bar forces or less (3). Since the arrows reverse for adjacent joints, draw them only on the truss but not on the polygon. Arrows pushing toward the joint are in compression arrows pulling away are in tension. A k-truss in a graph is a subset of the graph such that every edge in the subset is supported by at least k2 other edges that form triangles with that. Transpose arrows to respective bars in the truss next to the joint. Start with direction of load AB and follow polygon ABHGA with head-to-tail arrows. Parallel to bar HG through G to find H at intersection BH-HG.Į Measure the bar forces as vector length in the polygon.į Find bar tension and compression. Vector parallel to bar BH through B in the polygon. The graphical analysis was developed by force polygons drawn to scale for each joint, and then the forces in each member were measured from one of these force. With head-to-tail arrows are in equilibrium. Offset the reactions to the right for clarity.ĭ Draw polygons for each joint to find forces in connected bars. A closed polygon with head-to-tail arrows implies equilibrium. Name bars by adjacent letters: bar BH between B and H, etc.Ĭ Draw a force polygon for external loads and reactions in a force scale, such as 1”=10 pounds (2). Graphic truss analysis (Bow’s Notation) is a method to find bar forces using graphic vectors as in the following steps:Ī Draw a truss scaled as large as possible (1) and compute the reactions as for beams (by moment method for asymmetrical trusses).ī Letter the spaces between loads, reactions, and truss bars.
