  1. 328 INNOVATION BUILDING • COLLEGE TOWNSHIP, CENTRE COUNTY, PA • ` Anthony Pacitti Jr. Structural Emphasis Spring 2005 Senior Thesis Department of Architectural Engineering Consultant: Dr. Memari

  2. Primary Project Team Owner of Record: RMP Co. Development Of Record : Innovation Capital Partners, LP Architect : Robert L. Kimball & Associates Engineer: Robert L. Kimball & Associates General Contractor : Poole Anderson MEP : Subcontracted by Poole Anderson

  3. Existing Conditions • Location: • College Township, Centre County, Pennsylvania • Cost: • $10.1 Million for all onsite work, including tenant fit up allowances of $9.80 per rentable square foot • Size: • 3 stories with 73,943 sq. ft of tenant space • Functions: • Research and Development 10,000 sq. ft • Laboratories 20,000 sq. ft • Corporate Office Space 43,943 sq. ft • Project Delivery Method: • Negotiated firm price with a General Contactor, including a share of cost savings, provided the cost is lower than an established bench mark.

  4. Existing Floor System Typical Bay Consists of: • 3-W16 X 26 Interior Beams • 2- W24 x 26 Girders • 1- W16 x 26 , 1- W18 x 40 Connecting Into Columns • 3 inch Slab + 3 inch Deck Figure 2--Typical bay (30’-0” -39’-0”)

  5. K Joist Roof System 22 K 4 Joists supported by W24 x 68 Girder W16 x 26 Exterior Beam 1-1/2” 20 Gauge Type B Deck 2 W 24 x 55 Beams Were Added to Support the VAV Mechanical Systems Existing Roof Structure Typical Bay of Roof

  6. Existing Foundation • Square Footing and Strip Footing • Square Footings Ranging in size from 3’-0” x 3’-0” to 12’-0” x 12’-0” • Strip Footing Ranging in size from 1’-2” to 2’-0” Existing Foundation Plan

  7. Existing Lateral System • 6 Braced Frames • 4-North/South Direction • 2-West/East Direction • Seismic Controls • Typical Frames Are Composed of : • 2-W 10 Columns • Variety of W12, W16, W21, W24 and HSS Compression and Tension Members Existing Lateral System

  8. Redesigned Building Outline • Structural System • Flat Plate System without beams • Floor system • Columns • Shear Walls • Construction Schedule • Rescheduled for Concrete System • Electrical System • Resize Main Distribution Panel • Resize BUS-DUCT to Each Floor and In the Main Distribution Panel • Resize Breakers

  9. Goals for New Design • Direct Effect on the Schedule • Lower Overall Cost • More tenant Space with the Additional 2 Stories • Increase Floor to Floor Height

  10. Redesigned Building Size • 5-Story Building • Total Height = 75’-0” • 14’-0’ Floor to Floor Height • Additional 50,000 sq. ft of Floor Area

  11. Design Loads • DEAD LOAD = 165 PSF (12”/12)(150PSF)+(15PSF)FLOORING • LIVE LOAD = 80 PSF • Fy = 60,000 PSI • F’c = 4,000 PSI

  12. Direct Design Criteria • MINIMUM OF THREE CONTINUOUS SPANS IN EACH DIRECTION • LONG-SPAN/ SHORT-SPAN RATIO NOT GREATER THAN 2 • SUCCESSIVE SPAN LENGTHS IN EACH DIRECTION SHALL NOT DIFFER BY MORE THAN ONE 1/3 THE LONGER SPAN • ALL LOADS MUST BE DUE TO GRAVITY ONLY • SERVICE LIVE LOAD SHALL EXCEED TWO TIMES THE SERVICE DEAD LOAD

  13. Flat Plate System • Slab Thickness • ACI 9.5c -Table 13-1 • 12” slab • Computing the Static Moment • Exterior Panel • Negative Moment at the exterior end of the end span = 0.26Mo • Positive Moment in the end span = 0.52 Mo • Negative Moment at the Interior end of the end span = 0.70 Mo • Interior Panel • Negative Moment = -0.65 Mo • Positive Moment = 0.35Mo

  14. East –West Column/Middle Strip

  15. North-South Column/Middle Strip

  16. Moment Distribution

  17. Moment Distribution

  18. Design of Reinforcement

  19. Design of Reinforcement

  20. Design of Reinforcement of Moment Transferred By Flexure • Exterior Column • 58”effective width • 7 of the column strip bars and adding 6 #6 bars in the region • Interior Column • Reinforcement in the slab was sufficient

  21. Deflection • INTERIOR PANEL • DEAD LOAD =150 +50 =165 PSF • SERVICE LOAD = 165 + 80 = 245 PSF • CONSTRUCTION LOAD = 2*150 = 300 PSF  CONTROLS

  22. Deflection • Average deflection of the mid-spans of the column strips in one direction added to the mid-span deflection of the perpendicular middle strip. • Final deflection = 0.327 < l/360 and l/480.

  23. Columns • EXTERIOR COLUMN (FOR ALL FLOORS) • 22” X 22” • 4 #10 BAR • # TIES @ 18” • LAP SPLICE = 38” • INTERIOR COLUMN (FOR ALL FLOORS) • 22” X 22” • 12 #10 BAR • # TIES @ 18” • LAP SPLICE = 38 “

  24. Wind Wind Speed = 90 Exposure B Frequency = 3.07 Pressure = 12 psf Seismic Site Classification B Category 3 (Occupancy) Group 1 Cs = 0.04 T = .484 seconds Lateral System Design Loads

  25. Lateral System Design Loads SEISMIC – CONTROLLING FACTOR

  26. Lateral System Layout

  27. Shear Wall Design • Wall Thickness • 12” • 25’ Length • 17 # 5 bars @ 18 o.c. Vertical Reinforcement • #4 at 12”o.c Horizontal Reinforcement
