Abstract/Artist Statement

The Stockton Department of Public Social Services (DPSS) provides a wide range of social services for its citizens. During recent years, the facility has been evaluated to require a significantly higher level of occupancy. Our team developed an engineering design for a new location with a 5-story building and performed a seismic analysis of the structure to accommodate the needed capacity. The altered site incorporated a more welcoming atmosphere while utilizing sustainable design solutions. This involved improvement in storm water management, better allocation of space, and increased accessibility between facility lots. During the structural design, the five story building was modeled using RISA-3D structural analysis software. Loads were determined from industry standard building codes. Through an iterative optimization process in RISA-3D, the structure satisfied strength requirements. Using loading output obtained in RISA-3D, pile foundation dimensions were designed to satisfy weight, shear, and overturning caused by loading on the structure. Ensoft L-Pile, a soil engineering program, was used to model soil strength properties and concrete pile foundations. The seismic analysis was a two part development. The first consisted of the creation of a Response Spectrum Analysis (RSA) using MATLAB and the second was a Fluid Viscous Damper (FVD) system using ETABS. Base shears can be calculated using the earthquake specific information obtained from the RSA. With the ETABS model, FVDs were implemented to decrease story drifts from the original structural design. Finally, a cost analysis was completed to determine if the use of the FVD system was more effective in terms of life expectancy of the building.
