This document discusses how Timberlake Truss Works designs trusses to withstand the high winds in Kansas. It explains that they calculate structures to withstand wind speeds of 100-110 mph, beyond the 90 mph required by building codes, to ensure safety and durability. The company considers building usage categories and exposures to design trusses that can withstand Kansas' notorious prairie winds and the damage they cause.

1. Winds take a toll on
structures

2. Kansas is notorious for prairie wind

3. Causing millions in damage

4. That's why truss manufacturing
is so important!
Designed to:
-sustain high pressure winds
-keep people safe
-withstand Kansas weather

5. How do we do it??

6. WE CALCULATE:
Main Wind Force Resisting System
(MWFRS) and Components & Cladding
(C&C)

7. Building codes require withstanding
90-mph winds for inland areas...

8. BUT...

9. We design for wind speeds around
100 and 110 mph!

10. Less of this:

11. More of this:

12. Making sure we consider building
usage categories and building
exposures

13. Building usage:
Category 1: Building with low hazard
to human life
Category 2: substantial hazard
Category 3 & 4: critical facilities and
substantial hazard

14. Building exposure:
Exposure A: located downtown/city centers
Exposure B: urban & suburban surrounded by
similar buildings & trees
Exposure C: open areas with scattered
obstructions
Exposure D: unobstructed for at least a mile
over flat land

15. We DON'T take safety and durability
lightly!
