Seismic Analysis of Arkabutla Intake-Outlet Structures
Abstract
This report summarizes the dynamic finite element studies for the seismic evaluation of intake-outlet structures (intake towers and stilling basin walls). The seismic evaluation involves linear elastic finite element calculations for one- and two-dimensional models of an intake tower and two- dimensional models for the stilling basin. A response spectrum technique is utilized in the analyses. The work was conducted as a part of the Safety Assurance Program for the Corps of Engineers' inventory of flood control structures. The analyses were conducted to determine the adequacy of the Arkabutla Dam intake/outlet structures when subjected to a previously specified seismic event for the Arkabutla area. The analyses showed no major points of concern for safety of the structures. Some superficial damage would occur, but results show that the structure would be intact and operational following the specified event. The analysis assumes no foundation failures occur which would interact with the tower or stilling basin.... Earthquakes, Response spectrum analysis, Hydrodynamic interaction, Seismic analysis.
