3. Determine the following using the floor layout below. Assume this is an upper story in a multistory office building. Perform live load reduction as appropriate. The floor is subjected to service (i.e. unfactored) superimposed dead load of D = 2kPa and L = 3.6 kPa. Concrete weighs 23.6 kN/m3. Typical interior floor beam is 300 x 500 mm. Slab thickness is 100mm. Columns are 400x400mm square. Factored loads shall be taken as 1.2D + 1.6L. Use floor height = 4 m 3.1. Determine the service uniform load on a typical interior floor beam. 3.2. Determine the maximum factored bending moment on a typical interior floor beam assuming simple supports for each interior beam. 3.3. Determine the maximum factored shear on a typical interior floor beam.
