Seismic qualification of building roof structure
This paper presents a method for qualifying the existing roof structure of the Fuels and Materials Examination Facility (FMEF) at the US Department of Energy's Hanford Site in Richland, Washington. The roof is a safety class 1 structure and subject to the design-basis earthquake (DBE). The roof consists of 26 prestressed concrete T-beams 82 feet long spaced 6 feet on center. The beams support a 6-inch composite concrete top slab, roofing and insulating materials, and piping and associated equipment. The beams must withstand snow loads as well as the DBE. The piping and equipment are connected to the bottom of the beams through a continuous, embedded unistrut. Using the technique of decoupling the mass of the piping and equipment to compute the dynamic response of the beams essentially simplified the analysis to qualify the roof structure.
