A precast slab was employed for the floor of a building. The thickness and width of slab are 80 mm and 0.8 m, respectively. The effective span (or calculation span) is 3.0 m. 20 mm thick cement mortar and 10 mm thick lime were employed on the top and bottom of the slab, respectively. The density of concrete, cement mortar and lime are 25 kN/m', 20 kN/m' and 16 kN/m', respectively. Coefficient of structural importance is 1.0. The standard value of live load is 2.0 kN/m2. Requirement: (1) determine the uniform standard value of dead load ga and standard value of live load qr (the unit is kN/m). (2) determine the design value of bending moment at mid-span of the slab M (The load factors for dead load and live load are 1.3 and 1.5, respectively).

A precast slab was employed for the floor of a building. The thickness and
width of slab are 80 mm and 0.8 m, respectively. The effective span (or calculation
span) is 3.0 m. 20 mm thick cement mortar and 10 mm thick lime were employed on
the top and bottom of the slab, respectively. The density of concrete, cement mortar
and lime are 25 kN/m², 20 kN/m² and 16 kN/m', respectively. Coefficient of structural
importance is 1.0. The standard value of live load is 2.0 kN/m².
Requirement: (1) determine the uniform standard value of dead load g4 and standard
value of live load q (the unit is kN/m).
(2) determine the design value of bending moment at mid-span of the slab M (The
load factors for dead load and live load are 1.3 and 1.5, respectively).
