Uniform distributed load of slab on beam (4 m) = 34.8/4= 8.7 KN/m. Load of slab on beam (4 m)= area of trapezoidal*Wu = 8*8.7=69.6 KN. Uniform distributed load of slab on beam (6 m) = 69.6 /6= 11.6 KN/m. Complex-geometry Slab. Finite element modeling should beCustom to distribute the load of a slab with complex geometry to a beam. For this purpose, computer programs like SAP200, SAFE, and ETABS can beCustom.
