Seismic R Value if column for two mterials
Seismic R Value if column for two mterials
(OP)
I was quite confused how to deal with the R value for my roofed footbridge. I have a cantilevered concrete column and had my flooring and roof frame by structural steel. I assume the upper part being steel has different seismic response than than the supporting concrete column. Do i need to use two mathematical models when i wish get my seismic forces each material part?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
