Genetic Programming Approach for Prediction of Maximum Displacement Profiles of Plane Steel Moment Resisting Frames

This paper summarizes the results of an extensive study on the seismic response of plane steel Moment Resisting Frames (MRFs). A new relation to estimate maximum seismic displacement profiles of plane steel Moment Resisting Frames are proposed using genetic programming (GP) approach. This expression is obtained via a statistical analysis on the results of many hundreds of nonlinear dynamic analyses. Theinfluence of specific parameters is studied in detail. The OpenSees program is adopted for performing the nonlinear dynamic analyses of this paper. A comparison of the proposed method with the procedures adopted in current seismic design codes reveals the accuracy and efficiency of the former
