Abstract

ABSTRACT: A novel concept of multiple deterministic analyses is proposed to design safer and more damage-tolerant structures for seismic excitation. The underlying risk is estimated to compare design alternatives. The basic response surface method is significantly improved to approximately generate implicit performance functions explicitly. Using the advanced factorial design, moving least squares, and Kriging methods, nine alternatives are proposed and verified using Monte Carlo simulations. They correctly identified and correlated the damaged states of structural elements using only few hundreds of deterministic analyses. The authors believe that they proposed alternatives to the random vibration approach and Monte Carlo simulation.
