Description:
The Forest Park Condominiums, located in Anchorage, Alaska, consist of 12 single family units in six duplex-style buildings. The multi-story buildings are constructed on a sloped site utilizing wood framing and wooden foundations. The foundations consist of a wooden bearing wall, built-up pressure-treated columns on concrete footings, and wooden lateral bracing. The 7.0 Magnitude earthquake that occurred in Anchorage on 30 November 2019 caused structural damage in several of the units. Lateral cross bracing was overstressed during the earthquake and deflections of up to several inches can be observed in some braces. The brace connections appear to have failed and some columns are out of plumb.
The purpose of this project is to investigate the earthquake damage, assess the building’s existing lateral force resisting system, and design cost-effective repairs and retrofit. Modifications to the foundation shall adequately resist the lateral loads and ensure continued use and longevity of the building. Potential systems include new wood shear walls, a concrete shear wall, or steel bracing. Students will be responsible for 5-10% level schematic design for several alternatives, an alternatives analysis report, and then subsequently 25% design for the chosen alternative.
