The formwork plan for the beamed floor of a building is given above. There is 3 cm of coating mortar on the floors, 2 cm of marble coating, and 2 cm of plaster under the flooring. Beam widths are 0.3 m. Take the live load of 2 kN/m 2.8 mm diameter reinforcement shall be taken into account, net concrete cover is 15 mm, material is C25/30-B420C. Unit weights (kN/m 3 ): Reinforced concrete 25, coating mortar 16, marble 27 and plaster 20. (Answer questions 1-7 accordingly) QUESTION 1 L1=5 m and L2=4 m. Provided that the thicknesses of both slabs are chosen equal, what should be A the minimum thickness of D1 and D2 slabs? (Slabs should not require deflection calculation.)
