The book presents the trends in the main applications of structural optimization in civil engineering and building. This monograph, arranged according to subjects, furnishes a large number of optimization problems, formulated and solved for various kinds of structures: beams and frames, trusses and grids, columns and arches, hanging and lattice structures, etc. The aim of the book is to facilitate the application of the optimal solutions by the designers of civil engineering and building structures. For this purpose, the existing methods and solved problems are selected and presented with the necessary comments and explanations. Several examples are the results of the original investigations carried out by the authors, others are taken from selected papers published by leading world specialists. The book is directed to readers interested in the structural design, particularly to those whose active and creative
