Strengthening of existing structures to accommodate higher loads due to a change in use. Many of the existing buildings were designed for earlier versions of seismic codes and do not comply with the current standards. Upgrading these deficient structures would preserve the owner’s capital assets. TIDES has extensive experience in upgrading existing buildings to meet current seismic standards. Our experience includes using traditional techniques such as steel braces and concrete jacketing or using advanced fibre reinforced polymers (FRP) material.
