LBL Building 90
Seismic Strengthening
Berkeley, California
Building 90 on the campus of the Lawrence Berkeley National
Laboratory is a four-story, 88,000 sq. ft. structural steel office
building. Major components of the project included seismic
strengthening of the structure, reducing stresses in the structure due
to long term differential settlement, and stabilizing landslide areas
adjacent to the building. As architectural design consultant, murakami/Nelson’s
effort included the unique design of the exterior steel buttresses to
reinforce the existing steel frame building without affecting the
continued use of the building during construction.
