| Description: | Miscellaneous paper Abstract: A beam theory structural analysis was conducted on the 50-year-old Inner Harbor Navigational Canal at New Orleans. A moment of 122 ft-kips on a wall section having an allowable moment capacity of 49 ft-kips was determined when the lock was dewatered. However, there was no evidence of structural failure during previous dewatering operations. The moment at the wall section, determined from a three-dimensional finite element analysis, was 89 ft-kips, and stresses in the wall were less than yield stresses for the materials. The ultimate moment capacity of the section was found to be 94 ft-kips. Using the ultimate moment capacity of the section, when a load factor of 1.7 is applied to the loading and a capacity reduction factor of 0.9 is applied to the section as required by American Concrete Institute design procedures, the ultimate moment capacity of the section would be exceeded. A procedure is outlined to monitor lock wall deflections during dewatering operations to determine impending failure. |
