Remodel of 1922 Wood Home
Remodel of 1922 Wood Home
(OP)
A client would like to add a two story addition to an existing two story wood framed home that was built in 1922. The addition will add approximately 25% to the length of the building in the longer direction. Is there a "best practices" approach for the lateral analysis of the new portion? Should we add some mass and loads from the old building into the loads on the new portion? Should the new portion be stiffened beyond what is needed for itself to accomodate possible lateral loads from the old building? Is it ok to assume that the existing building is adequate laterally and design the new portion so as to add no new loads to the old building?
Is there any good reference material that deals with this situation?

To avoid having to analyse the "combined" structure, you can construct the new building adjacent to the existing with a lateral separation joint. There will be no load added to the existing building (vertical and lateral); only price you pay is having a "double wall".
