Concrete masonry unit (CMU) walls were rebuilt to replace the most heavily damaged masonry walls. For walls with minor damages but with more cracks, the FRCM technology was utilized.
ZFA Executive Principal Kevin Zucco said "When Simpson Strong-Tie brought FRCM to our attention, our confidence in them was at a high-enough level that we felt comfortable using a product that had not been used before in California. With Simpson Strong-Tie, we know the product support is there, we know the engineering background is there, and we know we’ll get the approvals that we need."
To prepare the team for the first-ever application of FRCM in California, mock-ups of the courthouse walls were built at a Simpson Strong-Tie research and development facility in nearby Stockton, CA, to practice installing the FRCM system. “From design support to field support, Simpson Strong-Tie was working with us hand in hand, and that made the process smoother and easier onsite,” says Pullman Project Manager Vivek Kumar in the video.
More About FRCM
FRCM systems are currently being introduced in the structural repair and rehabilitation industry as a new, effective strengthening technology offering reduced thickness, excellent durability, superior performance in high temperatures, and ease of installation versus traditional strengthening and repair methods
Since FRCM systems add less weight to the structure, they provide an excellent solution for strengthening concrete and masonry substrates, particularly in seismic retrofit applications. In addition to seismic retrofits, FRCM systems are ideal for the following applications:
- Strengthening aging, damaged, or overloaded structures
- Repairing and strengthening surfaces in a single application
- Correcting size and layout errors
- Matching existing substrate finishes
- Strengthening or repairing damp substrates, or substrates in harsh environments subject to high temperatures, humidity, abrasion, or ultraviolet (UV) radiation.
