    Cold Formed Steel and Steel Systems Not Specifically Detailed for Seismic Resistance

    you make a good point about reducing the base shear with a higher R value. the trade off of course comes in the detailing. I will respond again if I find anything more definitive. Thank you, --Matt B

    Cold Formed Steel and Steel Systems Not Specifically Detailed for Seismic Resistance

    Thank you both for your responses! structSU10, the cold formed section does not refer to an R=3 system, but it does not specifically exclude it either...and this is the way the code it often written, it's very particular about inclusions and exclusions. The references AISC 360 and AISI S100...

    Cold Formed Steel and Steel Systems Not Specifically Detailed for Seismic Resistance
