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

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
