No verification issue for horizontal straight pipes with no concentrated loads!

Based on Section 3 of Chapter 6 in \"Stress Analysis of Industrial Pipelines and Its Engineering Applications\", which deals with the distribution of basic loads – specifically the case of horizontal straight pipes without concentrated loads – a CII model was established for analysis. The stress conditions obtained were inconsistent with those predicted by the formulas. Based on the formula, within the limits permitted by SPAN, the load exerted on point B, regardless of its position between A and C, remains the same; that is, it corresponds to half of the total weight of the pipe over the distance A+B. However, the results obtained from software simulation do not match this formula. I would appreciate it if experts could help determine whether there is an issue with my simulation or a misunderstanding of the formula. Thank you! ! I would like to ask experts whether this approach to simulation is correct
For a continuous beam, try adding supports on both sides and imposing a twist restriction
