Structural optimization is used for different purposes, but generally minimizing construction costs and reducing structural damage when applying critical loads, including wind and earthquake, are major and common components in the optimization process. In this dissertation, various dimensions of optimal seismic design of skeletal structures using metaheuristic algorithms and chaos theory have been investigated.
Frequency constraint in truss structures as the main factor in controlling the behavior of truss systems, designing frames and trusses against loads such as wind and earthquake under various limit states on strength constraints and service conditions, as well as controlling the dynamic parameters of tuned mass dampers in improving structural behavior are some of the issues investigated in this dissertation.
In this dissertation, to achieve the optimal design in each of the proposed topics, by examining the strengths and weaknesses of the existing metaheuristic algorithms, new hybrid chaotic optimization algorithms are proposed. Based on the numerical examples obtained, the results illustrate a desirable performance of the algorithms.
