Quote:Your statement and paper clearly shows how important confinement
not for this reasons i linked, just to show where the building place and how about the others.
Quote:which one you trust your seismic map
seismic region maps will always be same, no slightly differences even for next years. differences are only in maximum ground accelerations scale in gravity (RS curve). is this structural or earthquake engineers problems?
Quote:well then will you design 100 story building in zone 1 or 2 using OMF where confinement requirement as in SMF is unnecessary?
from which i state, i designed a building with low ductility (OMF) in high seismicity regions (zone 1 or 2)? i just state "complex detailing and additional bars for full ductility requirements are unnecessary in low seismic regions"
Quote:Not good engineering decision if you speak about economics perspective.
economic is not always about money, for engineer is means material consumptions. are all engineers neglected? contradictions.
all argument i posted here's for explanations my agreement with budis,
Quote:... to use "normal" relation Framing Type & Seismic Zone - Seismic Design Criteria
and try to answering your questions and gave opinions (with citations) to your states,
Quote:(a) Just imagine, what if a building located in lowest seismic hazard are & use SMRF ? What's wrong with (a). I always use special moment frame whatever the zone is?
thx
