HEARST MEMORIAL MINING BUILDING SEISMIC IMPROVEMENTS, UNIVERSITY OF CALIFORNIA, BERKELEY

摘要

This paper describes the programming, planning, design, and analysis for the seismic improvements to a four-story brick masonry building originally constructed in 1907. The building is an historic landmark on the UC Berkeley campus, and is located very close to the Northern Segment of the Hayward fault. The selected system for seismic improvements is the installation of a high-damping rubber isolator system, in combination with fluid viscous dampers, and includes complete replacement of the foundation system and a new first floor system. The analytical procedures used, in combination with careful consideration of anticipated ground motions and reasonable performance goals, allowed the historic fabric of the structure to maintain its original appearance visually unencumbered by a new lateral force resisting system.
