Structural design for conversion of residential building to a commercial building at 182 N. Mar Vista Ave. Pasadena, CA\u00a0<\/strong><\/div>\n
<\/div>\n
\n
The project is a residence conversion to an office and a new 2 story building (Storage)<\/div>\n
includes comprehensive structural engineering services from load analysis through final construction documents. Structural calculations will be performed to determine wind, seismic, gravity and live loads, followed by the design of all key structural components including the roof, walls, foundations, beams and slab. Corresponding drawings will cover the structural plans and sections needed for construction, delivering a fully-coordinated design to safely support the new building from the ground up.<\/div>\n<\/div>\n\n\n

Design Challenges<\/strong>: <\/p>\n\n\n\n

The project presented several significant technical challenges:<\/p>\n\n\n\n

Heavy Loads: The structure needed to support a massive live load of 600psf.<\/p>\n\n\n\n

Seismic Mass: Due to storage conditions, 25% of the live load had to be included as seismic mass, necessitating an advanced dynamic analysis.<\/p>\n\n\n\n

Structural Optimization: The design had to account for P-delta effects and a redundancy factor (\u03c1), a linear dynamic analysis provided to safely optimize and reduce column and beam sizes.<\/p>\n\n\n\n

Site Constraints: The foundation size had to be minimized due to the close proximity of a neighboring building.<\/p>\n\n\n\n

S3DA Solutions:<\/strong><\/p>\n\n\n\n

Our team conducted extensive and advanced structural analysis to optimize the design for cost and safety. By performing a linear dynamic analysis, we accurately modeled the seismic behavior and structural response. This allowed us to precisely engineer the steel frame and column sizes, ensuring they met all code requirements without being over-designed. For the foundation, we developed a system that provided the required bearing capacity with a minimal footprint, respecting the tight property line constraints.<\/p>\n\n\n\n

Key Design Features<\/strong><\/p>\n\n\n\n

Advanced Structural Analysis: A linear dynamic analysis was performed to precisely calculate seismic demands and optimize the entire structural system for the high storage loads.<\/p>\n\n\n\n

BIM Coordination: The use of BIM was critical for coordinating the complex steel structure, ensuring all elements fit perfectly and preventing costly on-site clashes.<\/p>\n\n\n\n
