Seismic strengthening of an existing, historic unreinforced masonry (URM) building via “Center Core Strengthening”. To avoid impacts to the historic ceiling and interior/exterior wall finishes (e.g. hand-carved travertine, marble and wood veneer finishes and hand-sculpted/ painted plaster), Englekirk worked to develop a minimally invasive seismic strengthening scheme that was only possible with the “Center Core Strengthening” technique. Utilizing this technique, our final design accomplished a comprehensive seismic retrofit without removing or altering the existing interior/exterior wall or ceiling finishes – any removal of these finishes would have resulted in unrepairable damage. All in all, the extent of architectural impacts were limited to the removal and replacement of a 2′ strip of existing clay roof tiles along the roof perimeter.
