Eli- It looks as though you need to read section 2308 carefully to see what it specifies for your structure. I don’t think that section 1614.1 exception #2 relieves you from all seismic requirements – it simply says the structure isn’t required to be analyzed per section 1616.1.
As far as the IRC goes, we use it for single family structures. Of course, for lateral analysis you’re referred to ASCE 7-98 and IBC2000
We are taking the leap into IBC world up here in Washington, and I’m hashing through the lateral force provisions for design of an engineered single family home. I’ve noticed a tasty exemption in IBC2003 section 1614.1, exemption 2…basically stating that single family light frame designs in seismic design category A, B or C are exempt from ALL of the earthquake design sections (i.e. just design for wind). Is this wishful thinking, or am I missing something here?
As a related question, has anyone delved into the IRC?? Does this code apply to engineered single family structures, or only to prescriptive design? In other words, is the IRC only intended for architects and builders to use? I have heard of a case where a structural engineer was sued because they used the prescriptive design procedures in their design of a wood framed house. I guess the courts want to be sure us engineers actually use all those fancy buttons on our calculators.
