Construction Workout Schedule

Per Week

WBS

Overall Schedule

Pre-Bridge:

  • 1 Intense Running
  • 1 Team Game Day
  • 1-2 Individualized Cardio

Post-Bridge:

  • T/T Fieldhouse
  • M/W Brown Hallway
  • Quality Control
  • Design Team
  • On time completion of all documentation
  • Pre-submittal
  • Setbacks:
  • Fabrication (tabs vs. washers, member length, welding time)

Budget

Schedule

3 Components:

  • Overall Schedule
  • WBS
  • Construction/ Workout Schedule

Analysis/Modeling Cont'd.

Analysis/Calculations

  • RISA Modeling - consult experts for design review
  • Use resources - professors on campus
  • Have multiple skilled users - assign model reviewer

Competition

Analysis/Modeling

Lessons Learned

  • RISA - Symmetrical
  • Must add deflection accounting for maximum tolerance
  • P-delta Effects
  • Clarifications
  • 70% practice Load Test
  • Re-build - model changes
  • Check required distances (weld clearances)

Safety

Project Constraints

Competition Scoring

Fabrication

  • Gloves
  • Glasses
  • Long Sleeves
  • Welding Helmet
  • Quality Control
  • Cut sheets
  • Member cutting
  • Weld penetration
  • Fabrication
  • Safety
  • Competition
  • Analysis/ Modeling

Overall Performance:

= Construction Economy (Cc) +

Structural Efficiency (Cs)

  • Structure
  • Member Size
  • Deflection
  • Accessibility

Failure Analysis

Project Overview

  • Fabrication Failure
  • Quality control
  • Insufficient Modeling

Springfest 1.0

Springfest 2.0

Modifications

Points Of Failure

  • Added Cross Bracing
  • Lateral Stiffening
  • Construction time:
  • Raw time: 15 minutes 18 seconds
  • Penalties: 2 - 15 second penalties
  • Total construction time: 15 minutes 48 seconds.
  • Weight: 145
  • Clear distance penalty - 50lbs
  • Deflection: loss of structural integrity - 1150lbs
  • 46% of the total load
  • Construction time: Used results from springfest 1.0
  • Weight: 149lbs
  • Deflection: Structural failure - 1750 lbs
  • 70% of the total load

Challenge:

  • Design and Fabricate a 1:10 scale steel bridge prototype for the 2015 ASCE/AISC Student Steel Bridge Competition

Mission:

  • Minimize: weight, deflection, construction time

Overhead Truss

Fabrication

  • Benefits:
  • small amount of members
  • efficient connections
  • Ideal weight to deflection ratio

Fabrication Steps

Dovetails

  • Sent out for fabrication
  • Welded to connections

Main Truss Members

  • Mig Welded
  • Zimkor

Connections

Dove-tail Connections
