1–1. The Floor Of A Heavy Storage Warehouse Building Is
Made Of 6-In.-Thick Stone Concrete. If The Floor Is A Slab
Having A Length Of 15 Ft And Width Of 10 Ft, Determine The
Resultant Force Caused By The Dead Load And The Live
Load.
From Table 1–3
DL = [12 Lb/Ft2 . In.(6 In.)] (15 Ft)(10 Ft) = 10,800 Lb

From Table 1–4
LL = (250 Lb/Ft2)(15 Ft)(10 Ft) = 37,500 Lb

Total Load
F = 48,300 Lb = 48.3 K Ans.




1–2. The Floor Of The Office Building Is Made Of 4-In.-
Thick Lightweight Concrete. If The Office Floor Is A Slab
Having A Length Of 20 Ft And Width Of 15 Ft, Determine
The Resultant Force Caused By The Dead Load And The
Live Load.

From Table 1–3

DL = [8 Lb/Ft2 . In. (4 In.)] (20 Ft)(15 Ft) = 9600 Lb

From Table 1–4

LL = (50 Lb/Ft2)(20 Ft)(15 Ft) = 15,000 Lb
Total Load
Ans.
F = 24,600 Lb = 24.6 K




1–3. The T-Beam Is Made From Concrete Having A 40 In.
Specific Weight Of 150 Lb/Ft3. Determine The Dead Load
Per Foot Length Of Beam. Neglect The Weight Of The
Steel Reinforcement. 8 In.

During Highway Construction. Determine Its Weight Per
Foot Of Length If It Is Made From Plain Stone Concrete. 4 In.

1–5. The Floor Of A Light Storage Warehouse Is Made Of
150-Mm-Thick Lightweight Plain Concrete. If The Floor Is A
Slab Having A Length Of 7 M And Width Of 3 M, Determine The
Resultant Force Caused By The Dead Load And The Live Load.


From Table 1–3
DL = [0.015 Kn/M2 . Mm (150 Mm)] (7 M) (3 M) = 47.25 Kn

From Table 1–4
LL = (6.00 Kn/M2) (7 M) (3 M) = 126 Kn

Total Load
F = 126 Kn + 47.25 Kn = 173 Kn Ans.

1–7. The Wall Is 2.5 M High And Consists Of 51 Mm × 102 Mm
Studs Plastered On One Side. On The Other Side Is 13 Mm
Fiberboard, And 102 Mm Clay Brick. Determine The Average
Load In Kn/M Of Length Of Wall That The Wall Exerts On The Floor.
2.5 M


Use Table 1–3.

For Studs

Weight = 0.57 Kn/M2 (2.5 M) = 1.425 Kn/M

For Fiberboard
Weight = 0.04 Kn/M2 (2.5 M) = 0.1 Kn/M

For Clay Brick
Weight = 1.87 Kn/M2 (2.5 M) = 4.675 Kn/M
Total Weight = 6.20 Kn/M Ans.
