Or, at least, an effective form of wall bracing, (prescriptive codes). Who really installs vinyl siding directly to studs? This video is an exaggeration.Mark K said:This is why you need to engineer homes and why they need to be built according to the plan.
DAF Welcome to the boardHow long would the building stood if the door didn't fly open?
Actually, buildings can be designed to withstand breaches of the envelope. The just need to be designed as partially enclosed rather than enclosed. In their infinite wisdom (i.e. the need to support insurance carriers) the IRC does not allow for partial enclosure.mtlogcabin said:DAF Welcome to the boardAny breach in the building envelope will cause a failure that is why a lot of changes came into the codes after hurricane Andrew with regard to wind loads and windows and garage doors. Agree there should be something for all doors.
A good portion of building design is in the engineering assumptions. And the occupants ensuring the assumptions are true.brudgers said:Actually, buildings can be designed to withstand ... The just need to be designed as ...
Partially enclosed design can add to the cost of the structure, but structure tends to be cheaper than opening protection.GHRoberts said:A good portion of building design is in the engineering assumptions. And the occupants ensuring the assumptions are true.Typical tornado shelter design assumes that all 3 dead bolts are locked. Without that the door fails and the engineering changes.
One can assume that in a hurricane 3 dead bolts in the door will keep the door closed, but someone needs to lock them.
So does one pay a lot more for a "partially enclosed design" or does one trust the occupant to lock the doors? It is tough to set design standards.
