Elevation of building

Details of buildingGrade of concrete = M 20Grade of steel = Fe 415Column size = 300 X 450 mmBeam size = 300 X 450 mmLive load on floor = 3 kN/m2

Live load on roof = 1.5 kN/m2

Floor finishes 1 kN/m2 and roof treatment 1.5 kN/m2

Floor to floor height = 3.1 mDensity of concrete = 25 kN/m3

Density of masonry wall = 20 kN/m3

Plinth height above GL = 1.2 m

Assume suitable load combinations and design parameters

Apply the live, floor finish and roof treatment as floor load
