T Plant canyon deck-level allowable floor-load study
T Plant is to become a decontamination facility for the Hanford Site. This mission will require that large pieces of equipment be installed on the deck-level floor of the canyon in 221-T building. The objective of this study is to determine the maximum loads that can be applied safely to the canyon deck-level floor. These loads are caused by the weight of installed equipment. These load limits are to be used as design limits for the installation of the new equipment. The load limits for normal operating conditions are based on American Concrete Institute (ACI) 318.1 permissible stresses. The various floor configurations in building sections 1 through 20 are considered. Cover blocks are considered to be installed in all deck openings to create the worst possible case. The building is designated as safety class 3. The internal stresses, resulting from the inertial forces caused by the concrete during horizontal seismic accelerations, are out of scope for this report. They are considered in the seismic analysis of the building section. Vertical reactions when equipment is subjected to overturning moments during horizontal seismic accelerations must be determined and applied as part of the floor load. The new equipment to be installed has relatively small mass compared to the building weight, and there is a 25% reduction in the load factor during seismic events. Thus, the seismic effects are expected to be accommodated within the envelope of this static analysis.
