Identify the type of support at each location along the beam

Click For Summary
SUMMARY

The discussion focuses on identifying the types of support at points A, B, C, D, and E along a beam in a structural analysis problem. Points A and E are confirmed as fixed supports due to the distribution factor of 1, while the types of supports at B, C, and D remain unclear. The author expresses confusion over the differing carried forward factors of 0 and 0.5 used at these points, suggesting a potential error in the original analysis. The conclusion emphasizes the need for clarity in support types and consistency in carried forward factors.

PREREQUISITES
  • Understanding of structural analysis concepts
  • Familiarity with support types in beam theory
  • Knowledge of distribution factors in structural engineering
  • Experience with analyzing carried forward factors in beam calculations
NEXT STEPS
  • Research the different types of beam supports and their characteristics
  • Study the principles of distribution factors in structural analysis
  • Learn how to calculate and apply carried forward factors in beam problems
  • Review case studies involving fixed and roller supports in structural engineering
USEFUL FOR

Structural engineers, civil engineering students, and professionals involved in beam analysis and design will benefit from this discussion.

Homework Statement


I have problem with the carried over factor in photo 670 . It's not stated the type of support at point A , B , C , D and E . But , at joint at A and E , it's fixed support because the author use distribution factor of 1 at A and E ( in photo 669)

Homework Equations

The Attempt at a Solution


But , i am not sure what type of support at B , C , D are . For the green arrow , we can see that the author use carried forward factor of 0 , but for the 2 red arrows , we can see that the author used carried forwards factor of 0.5 . I 'm confused now . What type of supports at B , C , D are ? I think the author made the mistakes here . He can't use different carried forward factor , which are 0 and 0.5 at the support B , C and D .

Hi a, anyone can reply ?
 
I think the author made the mistakes here . He can't use different carried forward factor , which are 0 and 0.5 at the support B , C and D .
