Homework1 Calculate the distributed dead load Ibft for beams

Homework1 Calculate the distributed dead load (Ib/ft) for beams 2-5 and 3-6 for the frame below. Design Information 1\" Terrazzo Flooring Concrete Slab Steel Declk Ceiling Tiles & Supports Mechanical & Electrical Services 13 lb/ft 41 lb/ft = 3 lb/ft2 3 lb/ft x 10 y30 as 1 Beam = w14 x 22 1\" 3\" 3- Concrete Fl_ Steel Deck W14x22 Frame Construction Beams x on c.c Gridersy on c.c.

Solution

Tributary width of beam 2-5=X/2 + X/2 = 10/2 + 10/2 = 10\'

Total dead load in lb/ft² = 13+41+2+3+3=62 lb/ft²

Uniform dead load on beam 2-5 = 62*10=620 lb/ft

Self weight of beam = 22 lb/ft

Therefore, total dead load on beam 2-5= 620+22=642 lb/ft

Tributary width of beam 3-63=X/2 = 10/2 = 5\'

Total dead load in lb/ft² = 13+41+2+3+3=62 lb/ft²

Uniform dead load on beam 3-6 = 62*5=310 lb/ft

Self weight of beam = 22 lb/ft

Therefore, total dead load on beam 3-6= 310+22=332 lb/ft
