Identify the type of support at each location along the beam

AI Thread Summary
The discussion revolves around identifying the types of supports at points B, C, and D along a beam, where points A and E are confirmed as fixed supports due to a distribution factor of 1. The confusion arises from the differing carried forward factors at these points, with B, C, and D having factors of 0 and 0.5, leading to questions about the consistency of the author's approach. Participants express skepticism about the author's methodology, suggesting that using different carried forward factors at these supports may indicate an error. Clarification on the types of supports at B, C, and D is sought to resolve the inconsistencies in the analysis. The discussion emphasizes the need for accurate identification of support types to ensure correct calculations in structural analysis.

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 .
