  7. Abstract:
  8. Recent research in the field of earthquake engineering has seen the development of a number of different displacement-based seismic design (DBD) methods. Such methods aim to overcome limitations with the force-based design methods incorporated in current codes, and the most developed DBD method currently available is the Direct DBD approach, presented by Priestley. The objective of this work is to investigate the performance of the Direct DBD design procedure for steel moment-resisting frame structures. For this purpose, a series of regular steel MRF frames, varying from 4 to 20 stories in height are designed based on DDBD approach and utilizing displacement design spectrum of the Iranian Code of Practice for Seismic Resistant Design of Buildings (Standard No. 2800). The frames are also designed based on FBD approach to compare the results. The performance of the design approach is then gauged by running non-linear time-history analyses of models of the designed structures, subject to a suite of spectrum-compatible accelerograms. The peak displacements and story drifts recorded in the time-history analyses indicate that the new design approach can provide control of deformations and therefore damage
