Prior, to the solutions provided in the last questions segment duel. One of the students from one of the Eastern schools antagonized the workings provided, saying that three moment method, which was the method I used in determining the support moments, is wrong. In his claims he said that it has limitations that was why his lecturer don’t teach it. Below was the screenshot of his comment
The inside civil team explained to him that the three methods will give birth to same answer. In this post I tried solving with slope deflection and Hardy’s cross moment distribution method, the other last method has been solved before,for comparison check the last solutions provided in Q & A category.
Moment distribution method
Conceptually, like I commented MAB will be less than MBC. The above method employed in the midspan is not always advice able, but most designers apply it because it’s more easier to juggle with. I still stand to always apply the principle of similarity of triangle for salient moments. Though the diameter of rebar covers the whole.
