Problem 1: Load Distribution
The diagram is to support a 100 mm thick concrete slab. 5.8 kPa of dead load and 2.1 kPa of live
load will be overlaying on the slab. The following is the cross-section of the beams:
AB, GH = 250mm X 450mm
AG, BH = 250mm X 450mm
CD, EF = 250mm X 550mm
a)
Self weight
= (0.25x0.55x5.4) x 15
= 11.1375 kN-A
Tributary area
= 5.4x1.25+5.4x1.5
=14.85m^2
Self load
= (14.85x0.1) x 15
B
= 22.275KN
Dead load
=14.85x5.8
=86.13KN

Determine the following if the unit weight of concrete
is 15 kN/m3
a.
b.
C.
b)
Live load
Dead loads acting on beam EF.
Live load acting on beam CD.
Dead load acting on girder AG.
= 14.85x2.1
= 32. 185 kN
Total live load = 32.185
c)
Self weight
= (0.25x0.45x8.5) x 15
= 34.425 kN-A
Tributary area
= 2.7x8.5
= 22.95m^2
Self load
= (22.95x0.1) x 15
= 34.425kN
