This project deals with the problems of nonlinear hysteretic structures         subjected to random earthquake excitations.  The objective is to                develop a modal response spectrum procedure for the calculation of              structural responses such as member forces, deformation, and maximum            ductility.  Two approaches employing stochastic linearization are used          to analyze structures exhibiting hysteretic force-deformation behavior.         The approaches developed are iterative, employ the modal analysis               method of structual dynamics, and are able to provide response                  quantities such as member forces, member ductility requirements,                acceleration response and floor response spectra.  As a final product,          the research provides an analytical approach which should be of direct          help to structural engineers in their design evaluations of structures          for the earthquake design loads.
