Tunnels

Value Through Advanced Analysis

In high seismic regions, this technology is based on the performance based design philosophy adopted by many regulatory agencies. FEMA, UBC, ATC, and the California Department of Transportation (Caltrans) have all adopted this philosophy for the seismic design of their structures. Recently, SC Solutions engineers conducted designs and seismic evaluation of several tunnel structures in California using this performance based design philosophy, gaining extensive experience in designs that meet multiple seismic performance levels.
