SEISMIC EVALUATION & RETROFITTING

A successful solution requires thorough evaluation of the existing structure, extensive knowledge in the intrinsic characteristics of existing materials, and global understanding of retrofit solutions. Impact and interruption to the serviceability of the building during and after the retrofit construction must be weighed against actual benefits of a particular design.

North Justice Center, Fullerton, CA

The Trial Court Facilities Act of 2002 shifts the governance of California's Superior Court buildings from the counties to the state. The inventory comprises over 450 court buildings. Seismic Evaluation program as part of SB1973 identified a number of facilities that warrant further studies to identify their potential seismic risks and necessary rehabilitation.

Based on our site observations, review of existing structural drawings, Linear Dynamic Analysis performed based on FEMA 356, Pre-standard and Commentary for the Seismic Rehabilitation of Buildings, interim results were reported to the Office of Court Construction and Management Development for review.

Cypress College Humanities Building

This concrete building designed in the 1960s is evaluated based on FEMA 356 dual level criteria. The structure will be seismically retrofitted based on Division VI-R methodology under Division of State Architect's jurisdiction to meet the expected performance similar to new facilities.

UCSD Medical Center, Telecom Building

As part of the SB1953 program, it is necessary to seismically upgrade this essential facility to meet SPC-5 rating. Design team adopted a creative solution to allow seismic upgrade construction without interrupting the functions of the building occupants.
