structural fire design

• design a building
• find the fire load
• find time vs. temperature
• for fire
• for steel
• reduce E and fy
• perform member checks
• service dead and live load
• may require complete re-analysis to get loads
  correct
• design supplemental fire proofing to meet
  performance
