Tornado Shelter Design

December 13, 2017 @ 12:30 pm – 2:00 pm

Speaker: Jason Pirtle, PE
Jason Pirtle Structural Engineers, LLC

Devastating tornadoes causing loss of life and massive property damage have pushed the design industry into seeking new ways to protect the public during these events. With the 2015 requirement, structural engineers have been tasked with designing tornado shelters to do just that.

This SE University will cover the provisions of ICC/NSSA 500 and FEMA P-361 for which the shelter must be designed, as well as review issues and considerations specific to shelter design that aren’t often encountered in typical commercial design.


Learning Objectives:

After participating in this session, the learner will be able to:

  • Identify what types of facilities are required to have shelter per the 2015 IBC.
  • Describe the difference between a Shelter and a Safe Room.
  • List the factors that affect the calculation of wind pressures on storm shelters.
  • Describe how shelters are “designed” for wind-borne debris.


Handouts and registration emails for this session will be sent to SE University companies on Friday, December 8th.
