Re: 1633.2.5

If you look at "Ties & continuity" in the 1994 UBC 1631.2.5, the "dead plus
live load" portion is the only parameter that didn't change in the 1997
UBC.

Since I did not get an answer to my previious question " what is the load
combination used for concrete shear walls?" (must be too remedial) I will
try another question.

The UBC Section 1633.2.5 Ties and Continuity requires the girder, beam or
truss ties be designed for a horizontal force of a  0.5*Ca*I times the dead
load plus live load. My question is why is the live load included in this
force rather than the W load as defined in section 1630.1.1 ?
