Dear essenza
Thanks visit & participate in my thread.
I appreciate your effort adding info in my thread.
Response to your comment :
1) In my review I talk about :
- "pure relation Framing Type & Seismic Zone" ACI 318/318M 1999 & UBC 1997 ( & similar older buiding code )
- "pure relation Framing Type & Seismic Design Criteria" ACI 318/318M 2008 & ibc 2006 / ASCE 7-05
I did not talk abut our Indonesia Building Code.
2) I just want to remind our members when do design with ACI 318 using ETABS & SAP2000, must be careful with relation Framing Type & Seismic Zone - Seismic Design Criteria in case pure relation of ACI 318 & UBC or IBC
Point of my explanation can be explained in extreme examples below :
(a) Just imagine, what if a building located in lowest seismic hazard are & use SMRF ?
(b) Just imagine, what if a building located in highest seismic hazard are & use OMRF ?
Simply both extreme examples above are "improper design"
I suggest our members to use "normal" relation Framing Type & Seismic Zone - Seismic Design Criteria, & again I underline, I did not talk about our National Building Code
3) Flash about our Seismic Design Code ( Indonesia Seismic Design Code ) :
(*) Our Seismic Design Code, when you see at "reference" it said that one of reference for our seismic design code is UBC 1997, right ?
But, when you read carefully at UBC 1997 ( & NEHRP ) you will never find formula for "R" as in our seismic design code.
In UBC 1997 only said :
(*) Jakarta in UBC 97 is Zone 4 ( highest ), fact in our seismic design code Jakarta just Zone 3 of 6 ( where Zone 6 = highest )
4) Flash about Indonesia Concrete Code
When use ETABS / SAP2000 to design reinforced concrete building, be careful, we must edit the default parameters in ETABS / SAP2000 Concrete Design so that meet / match with criteria in Indonesia Concrete Code.
I'm glad if we together ( if possible ) can create a thread ( not in this tread ) specially all stuff related with our national code ?
Thx

In UBC 1997 only said :
Quote:1630.3.2 Determination of R.(*) About R, I prefer check actual R of my structure via pushover than formula in our seismic design code.
The notation R shall be taken from Table 16-N.
(*) Jakarta in UBC 97 is Zone 4 ( highest ), fact in our seismic design code Jakarta just Zone 3 of 6 ( where Zone 6 = highest )
