Port of Oakland Berth 22 Reconstruction

Seismic Design & Analysis

SC Solutions was contracted to evaluate the seismic performance of the proposed Berth 22 designs, particularly to properly capture the soil-structure interaction actions in three-dimensional space.  In developing the 3D model, the team developed these characteristics to enable the whole system to be designed to perform under various seismic events.

Application of the advanced analytical procedures coupled with the application of the performance based MOTEMS Criteria provided designers all the necessary information to address many key performance issues including:

• Determination of Wharf Performance for multiple performance levels,
• Investigation of Various  Pile Head Details,
• Investigation of  Dike Geometry Effects,
• Explicit  Consideration of Dike Movement.

Analytical process included both pushover and more rigorous time history analysis.  The information obtained during the analysis provided considerable insight into the behavior of the structural system.
