Calculate the weight of each of the slabs based on the following data: The project is a 574 m2 building for the use of operations offices for the ArTech company. The building consists of a ground floor (Level +0.0), a mezzanine level (Level +3.0 m) and a roof terrace (Level +6.0 m). The construction system consists of a reinforced concrete structure. Figure 1 (a) shows the architectural plan of Level +0.0, Figure 1 (b) the level +3.0 m and Figure 1 (c) the level +6.0 m. The spaces are delimited with dividing walls with a partition or table-rock system, see Figure 2. (Figure 1 Architectural plan: (a) Ground floor, (b) Mezzanine level, (c) Roof )

Materials: Concrete is considered to be M28 (28 MPa) and reinforcing steel is G42 (414 MPa). Consider that the rods on the market are: # 3, # 4, # 5, # 6 and # 8.
Loads: The loads to consider are dead and alive. The magnitudes of the loads must satisfy the requirements of the Construction Regulations for the Federal District. Consider that the electrical, lighting, hydraulic, sanitary and air conditioning installations are typical for an office building. The floor consists of 10 mm thick ceramic pieces (density = 17 kN / m3) and a 3 mm floor glue (density = 14 kN / m3). The facade walls are hollow pieces of mortar.
Structural system: The floor system consists of ribbed slabs in two directions perimeter supported on beams to form reinforced concrete frames. The total depth of the slabs is 25 cm, with 15 cm wide ribs and a 5 cm compression layer. The lightener are removable 60x60 cm. The upper part of the beams is embedded in the slab making a monolithic casting.
