A403.2 Scope of analysis.

This chapter requires the alteration, repair, replacement or addition of structural elements and their connections to meet the strength and stiffness requirements herein. The lateral-load-path analysis shall include the resisting elements and connections from the wood diaphragm immediately above any target story to the foundation soil interface. Stories above the uppermost target story shall be considered in the analysis but need not be modified. The lateral-load-path analysis for added structural elements shall also include evaluation of the allowable soilbearing and lateral pressures in accordance with the building code. Where any portion of a building within the scope of this chapter is constructed on or into a slope, the lateral force-resisting system at and below the first story above grade plane shall be analyzed for the effects of concentrated lateral forces caused by this hillside condition.
