Features: This book systematically elaborates on the fundamental principles, methods, and processes for judging structural stability through simple models. By studying the elastic stability of columns, it introduces the change in member stiffness under axial force, the elastic-plastic performance of steel structure member sections, the phenomenon of plastic flow in sections, and the numerical integration methods for elastic-plastic buckling of columns. It also covers various variational principles and approximate analytical methods and finite element methods based on variational principles. The book provides a detailed explanation of frame stability, shear buckling, the interaction between shear and bending buckling, elastic and elastic-plastic stability of variable-section members, the stability of dual lateral force-resisting structures, classification of frame structures, the stability of bending-torsion members, and the method for calculating in-plane stability of frame columns based on overall-story buckling. It also introduces the fundamentals of nonlinear analysis, the drag-coordinate method for geometric and material nonlinear analysis of frame structures, the rigid-body test for the stiffness matrix of nonlinear analysis elements, and the generalized stiffness parameter method for incremental-iterative calculations. The stability of arches is also studied.
