“…These constraints need to be imposed at each desired time instant. The consideration of all the constraints requires an enormous amount of computational effort and, therefore, treatment with a vast number of time history responses is a challenging problem for most numerical optimization algorithms (Zou and Chan, 2005). Various numerical techniques exist for treating such time-dependent constraints (Arora, 1999).…”

“…In recent years, several researchers (Lagaros et al, 2006;Zou and Chan, 2005;Kocer and Arora, 2002) have used traditional and evolutionary search techniques to optimize the seismic design of structures by using the response spectrum or THA. Salajegheh and Heidari (2005) incorporated a neural network, as an artifi cial intelligence technique, in the optimization process to predict structural time history responses.…”

The optimal seismic design of structures requires that time history analyses (THA) be carried out repeatedly.This makes the optimal design process ineffi cient, in particular, if an evolutionary algorithm is used. To reduce the overall time required for structural optimization, two artifi cial intelligence strategies are employed. In the fi rst strategy, radial basis function (RBF) neural networks are used to predict the time history responses of structures in the optimization fl ow. In the second strategy, a binary particle swarm optimization (BPSO) is used to fi nd the optimum design. Combining the RBF and BPSO, a hybrid RBF-BPSO optimization method is proposed in this paper, which achieves fast optimization with high computational performance. Two examples are presented and compared to determine the optimal weight of structures under earthquake loadings using both exact and approximate analyses. The numerical results demonstrate the computational advantages and effectiveness of the proposed hybrid RBF-BPSO optimization method for the seismic design of structures.

Seismic design of Reinforced Concrete (RC) dual systems is performed as an optimization problem for which the charged system search algorithm is utilized as an optimizer. An efficient structural modeling is also presented for this purpose. Here, first databases are created based on ACI seismic criteria for beams, columns and shear walls. Formulations for optimal seismic design of dual systems (shear wall-frame) are proposed. With some modifications on these formulations, optimal seismic design of RC moment frames can also be performed. This procedure is along with ordinary design constraints and effective seismic design constraints. These constraints consist of beams, columns, shear wall design criteria, and some other seismic provisions. Cost of the structure is considered as the objective function. According to the results of the numerical example, the proposed methodology can be considered as a suitable practical approach for optimal seismic design of reinforced concrete shear wall-frame structures.
