Computing axis forces of a construction

Click For Summary

Discussion Overview

The discussion revolves around computing axis forces in a construction problem, specifically focusing on identifying zero-force members and determining starting points for calculations. The context appears to be homework-related, involving structural analysis methods.

Discussion Character

  • Homework-related, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant seeks advice on where to start computing axis forces after calculating R forces.
  • Another participant suggests starting with the node method at the top of the structure.
  • A follow-up request for identifying zero-force members is made, indicating uncertainty about which bars do not carry axis forces.
  • A participant prompts for clarification on which members might be considered zero-force and encourages sharing of the participant's work to identify where they are stuck.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants offering suggestions and seeking further clarification without reaching a consensus on the specific zero-force members or the approach to take.

Contextual Notes

Participants have not provided specific assumptions or definitions regarding zero-force members, and there are unresolved steps in the calculations that may affect the analysis.

Hi all, I'm trying to compute the axis forces in the construction I put to attachment. I already have computed the R forces, but I don't know where should I start computing the axis forces from, from which point.

Could please someone give me some advice?

Thank you very much,
best regards.

You could start by applying the node method at the top.
 
Thank you very much, Cyclovenom!

However, I'm still not able to finish the exercise. Could you please advise me which of the bars are zero-force? (I mean they have a zero axis force).

Thank you in advance.
 
Which members without doing the problem you think are zero force members?

Where are you stuck? maybe you can show your work and we can see why are you stuck.
