This book is an outcome of academic cooperation between the Volgograd State University of Architecture and Civil Engineering in Russia, Stellenbosch University in South Africa and the Technische Universit„t Berlin in Germany. The authors performed coordinated and cooperative research on nonlinear structural analysis and on computer-supported civil engineering over a period of several years. Many of the innovative aspects of this book were invented and developed in the course of the research effort.

The availability of computers has, in real terms, moved forward the practice of structural engineering. Where it was once enough to have any analysis given a complex configuration, the profession today is much more demanding. How engineers should be more demanding is the subject of this book. In terms of the theory of structures, the importance of geometric nonlinearities is explained by the theorem which states that "In the presence of prestress, geometric nonlinearities are of the same order of magnitude as linear elastic effects in structures. " This theorem implies that in most cases (in all cases of incremental analysis) geometric nonlinearities should be considered. And it is well known that problems of buckling, cable nets, fabric structures, ... REQUIRE the inclusion of geometric nonlinearities. What is offered in the book which follows is a unified approach (for both discrete and continuous systems) to geometric nonlinearities which incidentally does not require a discussion of large strain. What makes this all work is perturbation theory. Let the equations of equilibrium for a system be written as where P represents the applied loads, F represents the member forces or stresses, and N represents the operator which describes system equilibrium.

Structural Analysis Fundamentals presents fundamental procedures of structural analysis, necessary for teaching undergraduate and graduate courses and structural design practice. It applies linear analysis of structures of all types, including beams, plane and space trusses, plane and space frames, plane and eccentric grids, plates and shells, and assemblage of finite-elements. It also treats plastic and time-dependent responses of structures to static loading, as well as dynamic analysis of structures and their response to earthquakes. Geometric nonlinearity in analysis of cable nets and membranes are examined. This is an ideal text for basic and advanced material for use in undergraduate and higher courses. A companion set of computer programs assist in a thorough understanding and application of analysis procedures. The authors provide a special program for each structural system or each procedure. Unlike commercial software, the user can apply any program of the set without a manual or training period. Students, lecturers and engineers internationally employ the procedures presented in in this text and its companion website. Ramez B.
