Why is the sign for bending moment negative when calculating it for free standing beams with positive moments about supports due to self-weight? - Quora
Civil Engineering Portal - Role of bent up bars, To resist negative bending moment at support. To resist shear force which is higher at support. To make structure economical by reducing amount
