Reasons for no response:
1. The question wasn?t really easy.
2. No politics are involved.
3. The specific code wasn't mentioned.  I opened 3 books before I discovered
section 1633.2.5 in the 1997 UBC.

Answers:
1. My opinion would be Strength design values, specifically because the word
"strength" is used in the first paragraph, and almost all seismic forces in
the 1997 UBC are in strength design values.
2. I interpret the second paragraph to mean that the (D+L) value is the
TOTAL load on the beam.  I also interpret that by "connection" it doesn't
mean a SINGLE connection.  If it is a single connection, then it needs to
resist the total load.  If the "connection" consists of TWO connections (one
at each end), then each end needs to resist approximately one half the load,
adjusted for diaphragm and drag forces.

Subject: 1633.2.5 Ties 

 I sent this a few days ago, got a notice it didn't go through so I'm trying
again. Sorry if I'm repeating myself.
 
 
RE: 1633.2.5 Ties & Continuity
1.-Is the result of the formula in Allowable Stress or Strength Design
values?
2.-The beam, girder or truss ties requires V= .5*Ca*I*(D+L). Is (D+L) the
reaction at the end
of the beam or the total load on the beam?
Thanks for any enlightenment on this.
Macie
