The method of section in truss is an analytical technique used to determine the forces acting on the members of a truss. It involves cutting the truss at a specific location and analyzing the equilibrium of the resulting free body diagrams. By considering the forces acting on the cut members and the reactions at the supports, the internal forces in the truss can be determined. The method of section is particularly useful for analyzing trusses with complex geometries or loading conditions.
Structure of the Method Section in a Truss Analysis
The method section of a truss analysis report describes the steps taken to analyze the truss and obtain the results. It is important to present the method in a clear and concise manner so that readers can understand how the results were obtained.
General Guidelines
- Start by providing a brief overview of the truss analysis method. This will help readers understand the purpose of the analysis and the general approach that was taken.
- Describe the assumptions that were made in the analysis. This will help readers understand the limitations of the analysis and the conditions under which the results are valid.
- Explain the specific methods that were used to analyze the truss. This may include describing the software that was used, the mathematical models that were employed, and the experimental procedures that were followed.
- Provide details about the data that was used in the analysis. This includes identifying the sources of the data and describing how it was processed and prepared for analysis.
- Discuss the results of the analysis and how they were interpreted. This may include presenting graphs, tables, and other visuals to help readers understand the findings.

Question 1:
What is the method of sections in truss analysis?
Answer:
The method of sections involves cutting a truss at a specific section and analyzing the forces acting on the cut members and the equilibrium of the truss on either side of the cut.
Question 2:
How is the method of sections used to determine the internal forces in a truss member?
Answer:
By cutting the truss at the desired member and analyzing the internal forces on the cut members, the force exerted by the member on the rest of the truss can be determined.
Question 3:
What are the limitations of the method of sections in truss analysis?
Answer:
The method of sections is only applicable to trusses that are statically determinate and cannot be used to analyze trusses with redundancies or unknown external reactions.
That’s about it for this crash course on the method of sections. As always, practice makes perfect, so keep scribbling those diagrams and crushing those calculations. Thanks for hanging out and giving this article a read. Swing by again soon for more truss-tastic adventures!
