The examples in this document are for two-story X bracing. I'm looking for the design for X bracing with bracing crossing each other between the floors.

I usually assign those loads the pair of diagonal angles to the nearest column. I don't see that kind of angle diagonal bracing in your details.

Not a lot of space to put braces (just exterior walls allowed). SCBF is not accepted by local code (R-001 from the Dominican Republic)

The referenced book is "Seismic Design Review Workbook"? Hehe.. Frankestein.

Is there any AISC document with the correct design and detailing for one story X brace for Special Concentrically Braced Frames (SCBF) I can see the example in the seismic design manual for the two-story X-bracing with the beam in the middle, but there is no reference to the one-story X-brace...

Is a Special concentrically braced frame (SCBF) embedded in an Intermediate Moment Frame (IMF) accepted as a Dual system as per ASCE 7? Or they should have different locations to be accepted.

Is a SCBF embedded in an IMF accepted as a Dual system? Or they should have different locations to be accepted.

Thanks a lot, Those were very valuable opinions.

Help!

Is it possible to combine AISC 358 Endplate prequalified connection with RBS? Usually SMF are controlled by deflection and shape required are so strong that D/C ratios below 0.2. There is any hint on codes than indicated that I can reduce the beam (RBS) to use a smaller but still properly...

I'm searching for an exception for Metal Buildings construction.

There are lots of clues on the code say the idea was to apply exceptions to the ordinary systems. Like assigning a Rd (Ro on ASCE7) value.

AISC Design Guide 7 is a good reference also.

Any idea on this?

I'm checking the R001 seismic code for Republica Dominicana and couldn't find ordinary systems as OMF or OCBF are permitted under any exception. Does anybody know if this code has exceptions for ordinary systems?
