Behavior of Underground Box Conduits in the San Fernando Earthquake of 9 February 1971.
Abstract
A study of the behavior of two flood control channels in the San Fernando earthquake of 9 February 1971 is presented. The report concentrates on the underground conduit reaches of these channels. A detailed account of the heavily damaged areas is presented. Correlations are made between tectonic movements and the behavior of the conduits. One conduit was crossed by a segment of the main fault break. Points on either side of the break experienced vertical, transverse and longitudinal offsets of about 4, 6.5, and 4 feet, respectively. Extensive areas of the conduits suffered failure of the walls due to lateral loads. Evidence of plastic hinge formation was encountered. (Author)
