Abstract
This research continued the development of a method which ultimately would enable earthquake engineers to make confident earthquake resistance guarantees. The method, applied to existing structures, leads to assessments of their earthquake resistance. The assessments appear to be somewhat conservative but consistent with the design practices among experienced engineering firms. This method, described in this report, may be relied on by civil engineers in the design, and in design reviews, of structures in seismic regions. Several modifications and extensions of the method are possible. Their application in practice is likely to be most appropriate for structures whose social or economic value invites conservative design, and some care and investment in the way it is achieved.
