1. Design of Proposed Wind Turbine Tower Testing Facility at the University of Wyoming Original Design (Fall 2011): Wade Burkett Margaret KimblePresented by Margaret Kimble Meadow Ridley Senior Honors Project 2012

2. Presentation Outline Facility Overview and Background Faculty Requirements Design Concept Proposed Changes and Areas of Further Design

3. Facility Overview and Background

4. Background Future of Wind Power Taller Towers Different Composition Advantage of Taller Towers Minimization of Obstructions Composition Steel Lattice Post-tensioned Concrete

5. Overview Tower Testing Multi-Axial Testing Strength Fatigue Axial

6. Facility Requirements

7. Load Requirements Crucial Loads: Stop of Rotation Moment and Wind Stop of Rotation Moment Wind Loads Tower Facility

8. Load Application Locations of Applied Loads Mounting of Actuator

9. Axial Load Results from Equipment on Top Tower Self-weight Collar Design Applicable for Testing of Lower Segments Specific to the Tower being Tested Connect Directly to the Foundation Pad

10. Operational Limitations Testing Conditions Wind Speed Limitations 50 mph

14. Facility Design Clear Zone Limitations on: Facilities Placement Personnel Location during Testing

15. Facility Design Wall Strong Shape Minimization of Concrete Ease of Construction Off-Site Ease of Transportation and Placement Multi-segment construction

16. Facility Design Wall Face Slabs (5 or 10 ft by 1 ft by 50 or 55 ft) Web Slabs (5 ft by 6” by 50 or 55 ft)

17. Facility Design Wall Connection

18. Facility Design Foundation Sizing Depth Plan Dimensions Reinforcement #11 bars Spacing: 4 in on center Two layers

19. Facility Design Piles 64 Tube Grid Spacing: 7 ft 6 in Edge Distance: 3 ft 9 in 16 in diameter Capacity: 400 kip

20. Facility Design Foundation Pad Steel Plate DYWIDAG Connectors

21. Loading Equipment Actuator: MTS 201.90 Capacity: 500 kip Stroke: 40 in Shoe for Load Application Pump: MTS 505.30 Flow Rate: 30 gpm Loading Rate: 34.5 in/min

22. Cost Estimate

23. Proposed Changes and Areas of Further Design

24. Proposed Changes and Areas for Further Design Strong Axis Design Inclusion of Buttress Full Height

25. Strong Axis Advantage Smaller Wall More Economic Disadvantage Limited Load Placement

26. Inclusion of Buttress Provides Stiffening for the Wall Allows for Greater Torsional Capacity Allows for Eccentric Loading

27. Full Height Testing Industrial Advantages Construction of Form Work Testing Advantages Reduction in Scaling
