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

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

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

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

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.

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

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.

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

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 + 1.6 (Lr or S or R) + (0.5L or 0.8W) 1.2D + 1.6W + 0.5L + 0.5 (Lr or S or R) 1.2D + 1.0E + 0.5L +0.2S 0.9D + (1.6W or 1.0E)

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 + 1.6 (Lr or S or R) + (0.5L or 0.8W) = 1.2(30k) + 0 + 0.5(30k) = 51k = 1.2(30k) + 0 + 0.8(12.5k) = 46k 4. 1.2D + 1.6W + 0.5L + 0.5 (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) + 0 + 0.5(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 (+)

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= 88.89 (unitless) Pu=4.71(E/Fy)^1/2= 113.43 If, KL/r < Pu Then, Fcr=[0.658^(Fy/Fe)]Fy Now, Euler’s equation: Fe=∏^2 E/ (KL/r)^2 = 36.22 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

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

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

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

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

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

Estimate

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

Construction of mini model A 1:12 scale model was designed Hinged roof 2 OHD doors Matted board for siding and roofing White felt for insulation Parts labeled by color
