As regards the SA procedure, it has proved an efficient search algorithm for the 4 case studies of walls, portal and box frames used in road construction and building frames. The study of earth retaining walls optimization shows that the inclusion of a limit of 1/150 on the deflection of the top of the walls is needed. Otherwise, results of the SA optimization are excessively deformable. Results of the optimization of portal road frames indicated the need of including the rarely checked ULS of fatigue in the list of structural restrictions for the optimization of road structures. The study of road box frames shows the importance of the inclusion of the SLS of deflections and the ULS of fatigue. The SA optimization of the 13 m free horizontal span box frame results in a slender and highly reinforced top slab. Results of the optimization of the building frame indicate that instability in columns and flexure, shear and deflections in beams are the main restrictions that condition its design.
