Genetic algorithm-based decision support for optimizing seismic response of piping systems

Journal of Structural Engineering, 131(3), 389–398.

By: A. Gupta n, P. Kripakaran n, G. Mahinthakumar n & J. Baugh n

Contributors: A. Gupta n, P. Kripakaran n, G. Mahinthakumar n & J. Baugh Jr.

TL;DR: This paper describes computational approaches used in a prototype decision support system (DSS) for seismic design and performance evaluation of piping supports and a novel seeding technique, which overcomes the inefficiencies of conventional methods in the context of pipe support optimization.
