Sustainable Technologies
Solar Panels Geothermal Heating/Cooling Rain Water Collection Green Roof
Solar Panels
Utilize a large grid-tied system • • Allow energy to be sold into the grid at low consumption times Avoid large battery bank; making the system easier to maintain and more eco-friendly Wirelessly monitor through a PC/Website 36 kW tower system consisting of 6 inverters and 180 panels
Geothermal Heating/Cooling
Vertical closed-loop system was developed by the mechanical group.
Reduce the Heating/Cooling costs and earn LEED credits
Rainwater Collection
Rainwater to be collected only from the main roof 20,000 Gal. tank proposed Irrigation to be north and west of building (Hatched area on following slide) No potable water will be needed for irrigation
Green Roof
Located on top of auditorium. Entrance on 3 rd floor of main building Green roof will feature extensive vegetation Extensive vegetation is lighter and requires less soil, thereby reducing the load (saturated load approximately 34 psf) Will feature walkways and tables for occupants to enjoy
Research Labs
Civil Experiments • Pervious Pavements • Green Roofs Electrical Experiments • Smart Grid • Wind Turbines • Solar Panels • Storm Water Collection • LEED Design Techniques Mechanical Experiments • Electric Motors • Hydrogen Fuel Powered Engines • Green Heating and Cooling Systems
Interior Concept
Exterior Plan
Utilize Kalwall Translucent Daylighting Systems Minimize need for artificial light Panels provide low solar heat gain and high insulation values Made from 20% recycled content
Exterior Plan – Glass
Strategically use windows to keep occupants in touch with outside world while providing natural light
Floor Layout
**Entrance windows and roof not shown for clarity
Structural Design
Structural Steel Frame Procedures followed: • Load and Resistance Factored Design (LRFD) • • American Society of Civil Engineers (ASCE) Version 7 American Institute of Steel Construction (AISC) Complete SAP 2000 v12 Analysis Hand Calculations for Typical Members/Sections • Floor Beams • Interior/Exterior Girders • Columns • Auditorium Roof • Main Roof • Wind Bracing • Foundation
Loads
1 st Floor • Dead = 200 psf 2 nd & 3 rd Floors: • Dead = 100 psf • Live = 80 psf • Live = 80 psf Auditorium Green Roof • Dead = 40 psf • Snow = 20 psf • Live = 80 psf • • Main Roof Dead = 40 psf Snow = 20 psf • Roof Live = 20 psf
SAP 2000
Floor Beams
Located on the 2 nd and 3 rd floors Designed to support metal decking with concrete cover Uniform distributed load on entire beam • Max load case: 1.2D + 1.6L
The beam was designed for the maximum bending moment Allowable deflection controlled beam selection
Interior / Exterior Girders
Designed using end reactions from connecting floor beams Point loads at girder/floor beam connections • Max load case: 1.2D + 1.6L + .5S
2 Typical interior and 2 exterior were designed Allowable deflection controlled girder selection
Columns
Designed using axial loading from SAP 2000 analysis – Max load: 1.2D + 1.6L + .5S
3 Typical columns (Locations on next slide) • Main exterior (Red) • • Main interior (Blue) Auditorium (Yellow) Maximum axial load controlled column selection
N
Auditorium Green Roof
Designed to support saturated green roof Distributed load on entire joist • Max load case: 1.2D + 1.6L + .5S
• Max span: 85 feet Long span LH series roof joist Allowable distributed load controlled selection
Main Roof System
Designed using supported tributary area Distributed load on entire joist • • • Max load case: 1.2D + 1.6L + .5S
Max span joist: 70’ Max span joist girder: 34’ 2 typical joists and 1 joist girder designed Built-up-roof components (per UT guidelines) • Metal decking • SEBS base sheet • Type 6 glass felts
Main Wind Force Resisting System
Based on ASCE 7 provisions Wind Load Factor = 1.6 (LRFD Combinations) 3 wind braces to resist East-West winds 2 wind braces to resist North-South winds 3 designs to accommodate structural differences in the building
Wind Brace Locations
N
Typical Wind Brace
Foundation Selection
Loadings obtained from SAP Analysis of the building Pad footings with integrated auger cast piles were selected Pad footings and piles required less concrete than strip or mat foundations The piles transmit some load to more stable clays below grade Four typical pad footings were designed to increase efficiency
Footing Design
Soil info was obtained from boring logs of Scott Park Estimated bearing capacity of 4 kips/sq ft for the soil Foundation size and number of piles determined by loading and bearing capacity Designed for one and two way shear to obtain sufficient depth for the reinforcing steel of the foundation
