russell foundation
Russell Foundation
  • Founded By Bishop Michael Russell and his Father

In 2003

  • Faith Based Community Development Organization
  • Renders Self-sufficiency Programs to Help Stabilize Families and Communities
  • Provides Jobs for Local Communities
  • Environmentally Friendly Initiatives
reasons for design
Reasons For Design
  • Reduce Traffic Congestion around Chicago-Indiana Area
  • Provide High Speed Transportation
  • Create Jobs in Indiana
  • Pioneering Environmentally Friendly Mass Transit Solutions
customer requirements
Customer Requirements

Bolted to cross-support

cross support
Cross Support

Box beam

Bolted to column

Supports rails

standard i beam w27 x 368
Standard I-Beam W27 x 368

Standard Size

Internal height equal to 25.43 inches

Fits standard 22 inch tire diameter

column support assembly
Column Support Assembly

All parts bolted and welded

types of steel
Types of Steel
  • Two common types used: ASTM A992 and ASTM 588
  • More common steel types reduce cost
  • High strength, low alloy steel, which used recycled metals
    • Saves on cost of manufacturing
    • Environmentally friendly
price comparison
Price Comparison
  • Consider long term maintenance and repair cost
  • Northwestern University experiment
    • A992 corrodes 64% more over time than A588
  • A992 would last less than half as long as A588 (weathering steel)
loading structure
Loading (Structure)
  • Deadweight Load
    • 80,000 lbs (355868 N)

per Rail

  • Braking Force
    • 9.8 m/s2 * 80,000 lbs
  • Fixed Supports
    • Base – Ground Interface
    • Open End Rails
shear stress structure
Shear Stress (Structure)
  • Maximum
    • 2.81 e7 Pa
total deformation structure
Total Deformation (Structure)
  • Maximum
    • 16.75 mm
  • Location
    • Mid-span
factor of safety structure
Factor of Safety (Structure)
  • Minimum
    • 6.15
  • Location
    • Beam-

Near Connection

loading beam
Loading (Beam)
  • Deadweight load
    • 40,000 lbs

per Flange

  • Fixed Supports
    • Open Ends of

Beam

fatigue life beam
Fatigue Life (Beam)
  • Minimum
    • 8.03e5 cycles
concluding remarks
Concluding Remarks
  • Our designed is based on the customer requirements and goals of the Russell Foundation.
    • The factor of safety meets required limit of 5-7
    • Fatigue life exceeded 8.0 e5 cycles
    • A588 steel resists weathering without excessive cost
    • Single column design minimizes footprint
    • Designed to easily integrate renewable energy sources
structure span length
Structure Span Length
  • Preliminary Testing
    • Larger Beam
      • 39 in. Interior Beam height
    • Factor of Safety Increased to 9.53
    • Custom Beam
      • Standard Size Not Available
