Originally constructed as a medical office building, this four-story, semi-circular structure will be the new home to Nova Academy located in Santa Ana, California. In order to meet the increased design criteria required to convert the existing building to a school building, a series of fluid viscous dampers were installed into the structure to supplement the existing pre-Northridge steel moment frame system.
Several unique factors on this project drove the usage of dampers, including the minimization of foundation work, improved building performance, and a tight schedule to complete the upgrade just in time for the 2016 school year. A performance based design of the structure was conducted, in accordance with the ASCE 41 Tier 3 guidelines, to determine optimal damper design and placement.
Nishkian Chamberlain worked closely with the architect, a team of peer reviewers, and the local building department to design a system suitable for the safety and functionality of students.
Nishkian Chamberlain also provided extensive construction support throughout the damper installation project, for those unexpected conditions that frequently occur in existing structures. This component proved critical to meeting the project’s rapid 5 month construction schedule.
When retrofitting buildings for improved seismic safety we strive to minimize construction cost and time, maximize benefits through performance-based design, and preserve historic appearance and fabric as appropriate. Context-sensitive solutions require both experience and innovation, using existing systems with new structural materials. Our experience includes unreinforced masonry, reinforced concrete, structural steel and wood framing.
