Los Angeles, CA
Lane Building, 8th and Spring Streets
Scope/Solutions
The historic Lane Building is a twelve-story, nonductile concrete structure originally constructed in the early 1920s. The owner undertook a renovation project to convert the building to a mixed-use property with ground-floor retail and more than 100 apartment units. SGH collaborated with the project team to design seismic strengthening that could be integrated with the proposed program, while maintaining the building’s historic character.
As the executive structural engineer for the seismic retrofit, SGH applied ASCE 41 to design structural strengthening that complied with the City of Los Angeles’s Non-Ductile Concrete Retrofit Program. Highlights of our work include the following:
- Evaluated the existing building structure
- Performed advanced performance-based nonlinear analyses, including soil-structure-interaction evaluations, which allowed us to optimize the design and save construction costs
- Designed the seismic upgrades, including new concrete shear walls and concrete moment frames, and strengthening with carbon fiber composites
- Participated in a third-party peer review process through which our analysis and design was reviewed by another structural engineer
