SPRUT — Analysis and Design of Flat Slabs Guide | SPRUT (EN)

Total design load along: The absolute sum of ve and +ve moment in a panel along: (i) Negative and Positive Design Moments: The negative design moment shall be at the fac e of rectangular supports, circular supports being treated as square supports having the same 31.4.5.1 Columns built integrally with the slab system area. Shall be designed to-resist moments arising from loads. In an interior span, the total design moment 0 M shall be distributed in the following proportions: Negative design moment 0.65 Positive design moment 0.35 In an end span, the total design moment 0 M shall be distributed in the following proportions: Interior negative design moment:
