Dennis, you wrote, "Years ago I designed quite a few second story additions in Los Angeles with this same concept. The second story was carried by post and beam construction and the shear transfers where made to the first floor "beefed-up" existing or new shear elements (walls, frames etc.). I believe that the City of Los Angles tried to outlaw (and may have succeeded) the design of post and beam second story structures. . . . Tim McCormick (who is a frequent contributor) may be prompted to respond to you about this one. . ... . As long as you tie the load path from the roof down to the foundation for gravity and lateral, I don't think this would be considered strictly a post and beam type structure. Check with the City of Los Angeles for the most conservative view."" Dennis, your last paragraph states our position. As long as the post-beam portion of the structure is properly connected to and laterally braced by sufficient shear walls (or equivalent methods), there is no concern with the vertical system using the post beam concept.
