1. Performance Based Design of a Steel Frame Hotel

2. Performance based design of a steel frame hotel
3 structural elements
Beam
Column
Wall
3 compartments
Guest room
Conference room
Kitchen
Performance Based Pyramid

3. Assumptions:
Geometric design of the hotel
3 Stories
20X20X12 ft bays
Design of compartments
Room dimensions and windows
Calculating the loads placed on each of the structural elements

4. Dimensions of the rooms
Finding total area
Finding total area of opening (windows)
Finding the ventilation factor
Find the maximum temperature

5. Hotel Guest Room
3 windows
20ft by 20ft
Fuel load is 495
Fv=.04

6. Conference Room
4 windows
20ft by 20ft
Fuel load is 760
Assuming the conference rooms to be the same as ‘Office’
Fv=.08

7. Hotel Kitchen
6 windows
20ft by 40ft
Fuel load is 740
The mean value
Fv=.08

8. Used Program Called Safir, to analyze the thermal and structural
Analyzing a beam and column
Protected and non-protected
Limiting criteria 550 Celsius
Beam
Using thermal analysis
No fire protection
With fire protection (insulation)

9. With fire protection (insulation)
Columns
Fire protection and non protection
No fire protection
Both beams and columns are over the limiting temperature criteria of 550 degree Celsius
Minimum of 30 mm of insulation is need

10. Beams
Structural analysis
No insulation
Beam fails in 25 mins
Required to have 90 mins or 1.5 mins
With insulation
Beam fails in 174 mins or 2.9 hrs
Well over required performance

11. Column
With insulation
Column does not fail at 4 hours
Well over the 2 hour performance criteria.
No insulation
Fails at 27 mins
Below the performance criteria of 2 hours.

12. Gypsum wallboard rating
The performance criteria is to have a one hour fire rating.
Type X
5/8 inch
Wall
One layer 5/8 inch Type X
Two layers 5/8 inch Type X
on the side most likely to be exposed to fire.

13. Conclusion Beams and Columns Need to have fire protection (insulation)
More then 30 mm
5/8” Type X gypsum wallboard
One side with one layer
Other side with two layers
Facing the side most likely to have a fire
