The Tyfo® system provides many retrofit solutions for vital civil infrastructure and has been used extensively on bridges, tunnels, elevated roadways, airports and other transportation infrastructure all over the world.
The Tyfo® system can be used to strengthen transportation infrastructure for the following reasons:
- Increase load ratings
- Seismic retrofit of structural components
- Rehabilitation of corroded or distressed members
- Maintain the appearance and overall aesthetics of historic bridges
- Extend service life
- Emergency repairs
- Construction error remediation
The very first research conducted on the Tyfo® system in the 1980s was on bridge columns for added strength and confinement. These tests were quite successful and led to the development of design procedures for various columns, beams/pier caps, walls, slabs/soffits and beam-column connections. Additional rigorous structural and durability testing was performed to gain acceptances from various city, county and state departments of transportation. The Tyfo® system provides a cost-effective solution and low impact, fast-track completion for most structural deficiencies.
