This useful article is authored by Dr TJ Sullivan with his former advisors, Professors MJN Priestley and GM Calvi. It explains a new procedure of seismic design of frame-wall structures based on displacement-based design method.

Abstract:

A displacement-based design (DBD) methodology for structures that are comprised of both frames and walls has been proposed and then tested through examination of several case studies. Strength proportions between walls and frames are decided before any analysis has begun. The various steps required to represent a frame-wall structure as a single-degree of freedom system are identified and a Direct DBD process is then adopted to set the required strength level. To test the design methodology, two sets of 4, 8, 12, 16 and 20-storey reinforced concrete structures are designed, with different proportions of the total strength assigned to the frames.
