Document Type: Proceeding Paper

Part of: Lifeline Earthquake Engineering: Performance, Design and Construction


The Century freeway (Interstate 105), will be an 18 mile (29 km) long, six-lane facility with 2 central transit/HOV lanes, located in Los Angeles, California. The freeway alignment crosses the Newport-Inglewood fault zone and seismic considerations are of primary importance in the design of the more than 200 structures in the project. The development of site-specific seismic response spectra is presented. The use of seismic resistant column and footing details based on the latest CALTRANS seismic criteria is discussed. The design considerations for pile shaft foundations are presented.
