  abstract =     "Welded beam-column joints play a fundamental role in
                 the global response of steel structures. The flexural
                 resistance and initial stiffness properties of the
                 joints are affected by different parameters. It is
                 idealistic to develop models, relating these properties
                 of the joints to the influencing parameters. This paper
                 proposes a novel approach for the prediction of
                 flexural resistance and initial stiffness of welded
                 joints by using a hybrid search algorithm that couples
                 genetic programming (GP) and simulated annealing (SA),
                 called GP/SA. Column height, column flange width,
                 column flange thickness, column flange yield stress,
                 column web thickness, column web yield stress, beam
                 height, beam web thickness, beam web yield stress, beam
                 flange thickness, beam flange width, beam flange yield
                 stress, and weld thickness are used as input variables
                 to the models. A reliable database from the previously
                 published literature was employed to develop the
                 empirical models. The accuracy of the proposed models
                 is satisfactory as compared to experimental results.
                 GP/SA models are further compared with the
                 corresponding design code (Eurocode 3) reference
                 values. The results demonstrate that the GP/SA based
                 models have better performance than Eurocode 3
                 models.",
