Draft Revision 4 - December 2012 structures. The ASCE 43-05 standard presents a graded approach to design/analysis of structures for loading combinations that include seismic loads. In accordance with ASCE 43-05, nuclear seismic Category I structures require the most stringent design criteria; namely, a linear elastic limit state. This is consistent with NRC guidance for design/analysis of Category I structures. ASCE 43-05 also addresses design/analysis of structures of less critical functions, allowing response beyond the elastic limit state, to a safe and predictable inelastic limit state. Such an approach is potentially applicable to satisfying Approach C, where there is sufficient gap to accommodate increased displacement of the non-Category I structure. VI. REFERENCES 1.
