Loads
Roof materials, metal roof instead of rubber membrane because of the live span of the metal that will
live longer. Steel 60 yrs. live span, and 30 yrs. live span for the rubber.
From the ASCE7-10(American society of civil engineering), The utilities building will be under risk
category 1 using the LRFD method.
Also using the ASCE7-10 and the IBC-2012:
Unit weight of the metal roof, 14-gauge metal roof has unit weight of 3.13 psf, and we accounted for
10% for the hardware weight therefore approximately 4 psf is the Dead Load for the building.
The roof live load is 20 psf for an ordinary monoslope roof.
Since the elevation of the park topo map is 10 ft, there is no need to include flood design.
Using the directional method, the building at exposure B and the minimum wind speed city of Mobile is
150 mph from the IBC-2012 (international building code). So, the qz=28 psf, and G= 0.85. The slope is
6.9o. Therefore, we calculated wind roof load of 29 psf, and wind wall load of 20 psf.
The intensity of 100 year/hr. rainfall is 4.5 in/hr. No ponding instability because of the roof slope exceed
1.19o. Hydraulic head of 1 in, and static head of 3 in. So, we got rain load of 20.8 psf.
Using the LRFD method we calculated six combinations loads, 8.4 psf, 17.6 psf, 54.98 psf, 46.6 psf, and
34.4 psf. And we choose the 54.98=55 psf as it the largest combination load.
Structure
Is going to be steel members consists of two beams and four girders and four columns. The team choose
the steel structure instead of the concrete walls because of the live span and the cost effective of the
steel than the reinforced concrete, and due to the fact that we required short space and cost effective
for the building.
Beams,
At= 46.75 ft2
KLL=2
At KLL= 93.5 ft2 < 400 ft2 Therefore, no reduction needed. LRFD, factored load Pu= 55 psf Wu= 151.25 lb/ft. Zx= 1.5 in3 So, from the Zx table we choose W8x10 beam. ... Purchase answer to see full attachment
