[QUOTE="scha2707, post: 2200391, member: 26859"] Not necessarily. As a Structural Engineer, I've designed several FEMA 361 compliant safe rooms that would have structurally withstood the 200+ mph winds. FEMA 361 document requires that you design for 250 mph winds which are on the extreme high side of an EF-5 tornado. The problem is that, I do not design the window and door closures and attachment to my structure. Therefore, if one of the windows or doors get sucked off the building that I designed is now experiencing loads and pressures that it was not designed for. However, if all components are designed to the FEMA 361 standards, it will stand through a tornado like this one. [/QUOTE]
