Carson Block Building Seismic Renovation


Location: Eureka, CA 

The Carson Block Building is a historic three-story wood-framed building constructed in 1892 with full-height URM walls at two exterior sides and basically “open-framed” walls at all levels at the other two sides.  It originally contained a two-story theater based at the second level.  The third level was infilled in the theater space during remodeling in the 1950′s.  CYS has evaluated the building using ASCE31-02 and is designing a full seismic renovation with the State Historic Code and FEMA 356.  The owner requires that our design accommodate restoring the theater in its original location, including removing the 1950′s third floor infill.  Also, the fly gallery above the stage must be expanded upward about 20 FT above the original roof.
