1. Southeastern Sustainability Center Addition
By: Andrew LeBlanc
ET-494
Fall 2013-Spring 2014
Advising by: Rudolph Rode and Byron Patterson

2. Objective
To design and construct a building in which has the following attributes:
24’x24’
Able to be multifunctional
Leave potential for future development

3. Overall vision
Self sufficient = Save $$$
Begin 10 year plan

4. Desires in Building: Pellet Mill functional Solar panels OHD door
Eye wash station
Fire sprinkler system

5. Basic parts Rigid frame column and rafter- main structural system
Girts and Purlins- secondary structural members
Posts- supports structural members
Jambs- doors, windows
X-Bracing- the lateral load on a building is reduced by transferring the load into the exterior columns.

6. Basic Connections Roof purlins- butt joint
Roof purlins and sidewall girts- prepunched holes
Columns- anchor bolts
Door jambs- open C channel and C sections

7. Flush and Bypass
Flush girts provide no air space between the columns and exterior panels yet offer the maximum amount of floor space.
The Bypass girt makes a continuous run around the outside of a building’s columns, providing an air space the width of the girt between the column and exterior panels.

15. Calculations- Types of loads
D = Dead load
L = Live load
LR = Roof live load
S = Snow load
R = Rain load
W = Wind Load
E = Earthquake load

16. LRFD Load Combinations:
Gives the overall compression or tension in members in steel buildings:
1.4D
1.2D + 1.6L + 0.5(Lr or S or R)
1.2D (Lr or S or R) + (0.5L or 0.8W)
1.2D + 1.6W + 0.5L (Lr or S or R)
1.2D + 1.0E + 0.5L +0.2S
0.9D + (1.6W or 1.0E)

17. LRFD (Load & Resistance Factor Design)
LRFD Load Combinations for Southeasten’s Sustainability Center Addition, given: D = 30kips, L = 30kips, W = 12.5 kips
1. 1.4D = 1.4(30k) = 42k
2. 1.2D + 1.6L + 0.5(Lr or S or R) = 1.2(30k) + 1.6(30k) + 0 = 84k
3. 1.2D (Lr or S or R) + (0.5L or 0.8W)
= 1.2(30k) (30k) = 51k
= 1.2(30k) (12.5k) = 46k
4. 1.2D + 1.6W + 0.5L (Lr or S or R)
= 1.2(30k) + 1.6(12.5k) + 0.5(30) + 0 = 71k
5. 1.2D + 1.0E + 0.5L +0.2S = 1.2(30k) (30) + 0 = 51k
6. 0.9D + (1.6W or 1.0E) = 0.9(30k) + 1.6(12.5k) = 47k
In which I found to be 84k compression (+)

18. Buckling load
A W8 x 28 section was selected for a pinned-pinned connection as follows; with a length of 12 ft.
K=1.0, ry=1.62, Fy=50Ksi (found in AISC manual)
Slenderness ratio: KL/r= (unitless)
Pu=4.71(E/Fy)^1/2=
If, KL/r < Pu
Then, Fcr=[0.658^(Fy/Fe)]Fy
Now, Euler’s equation: Fe=∏^2 E/ (KL/r)^2 = ksi
Plug in, Fcr=28.06 ksi= 28,060 psi
elastic buckling-slender columns that have a large slenderness ratio and failure is before any yielding in the materials.
inelastic buckling occurs for intermediate columns that have a moderate slenderness ratio and the failure occurs by both the buckling and the materials yielding simultaneously

19. Codes, Specifications and Standards Building Codes
Most used single national building code: the International Building Code (IBC)
Legal documents which protect public safety.
• Minimum design loads
• Detailed design, construction and inspection rules for structures in general
1) Building occupancy classifications
2) Building heights and areas
3) Interior finishes
4) Foundation, wall, and roof construction
5) Fire protection systems (sprinkler system requirements and design)
6) Materials used in construction
7) Means of egress

20. Specifications
Specifications are design guidelines and recommendations
ACI (American Concrete Institute)
3500PSI concrete is used for applications where significant loading is expected. Uses include building footings, bond beams, grade beams, and floor slabs where heavy loads may be moved or stored.
AISC (American Institute of Steel Construction)
Specification for Structural Steel Buildings
Code of Standard Practice for Structural Steel Buildings

21. Specifications 2500psi- walkways, driveways 3000 psi- standard
3500 psi- where surface spalling isn’t acceptable
4000 psi- heavy constant loads
2500 psi
3500 psi
4000 psi

22. Local codes and standards
Fire marshal and city of Hammond approval
Approves drawn plans by stamping ensuring they meet requirements such as:
NFPA 13, 13D, 13R - Sprinkler Systems
NFPA 17 - Dry Chemical Extinguishing
NFPA 10 - Fire Extinguishers

23. Estimate
an approximate calculation or judgment of the value, number, quantity, or extent of a job
Gives approximation of total project cost
Detailed description of materials used

24. Estimate

25. Time scheduling MS Project 2013 Total completion time: 6 weeks
Seven laborers working 40 hours weeks
Monday-Friday, 8am-5pm
Tracks progress and gives timelines to meet
Total cost:$22,500

26. Construction of mini model
