Program overview of the hollow clay tile wall program
Some of the facilities at the Oak Ridge Y-12 Plant were designed and constructed at a time when either the building codes did not require consideration of earthquake loads or the design requirements were considerably lower than current requirements specified by General Design Criteria, Department of Energy (DOE) Order 6430.lA. Also, some of the buildings were constructed with unreinforced infilled hollow clay tile wails (HCTWs), whose performance in past earthquakes continue to be of concern to designers and to code committees. Martin Marietta Energy Systems Inc. is in a phased program to update the safety documentation for existing facilities known as the Safety Analysis Report Update Program (SARUP). Phase I of SARUP identifies those facilities where natural phenomena (i.e. earthquake, wind/tornado and flood) loading is an initiating or contributing event to accident scenarios with potential human health effects and off-site consequences. Detailed quantitative evaluations are to be performed in Phase III to determine the effects of natural phenomena loadings on such facilities. The HCTW program was developed by the Center for Natural Phenomena Engineering to determine the contribution of HCTWs to the lateral-load-carrying capacity of steel and reinforced concrete frame buildings. The HCRW program consists of laboratory tests of unit tiles, assemblages of tiles, and HCT walls influed in steel frames; in situ tests of a full size wall and portions of walls; and analytical studies directed toward incorporating the test results into analysis methodologies for seismic structural analyses. This report gives an overview of the HC-RW program and presents an approach for applying the HCTW program results to meet DOE requirements for evaluating existing DOE facilities for natural phenomena hazards as defined in DOE 6430.lA. The program supports the Phase II SARUP evaluations for the Y-12 plant.
