This textbook aims to be the bridge between plate theory and FE-software. Structural engineers must translate elastic analysis results into economic structure dimensions and reinforcement, which raises difficulties. Not all engineers are well enough equipped for the increasingly easy-to-use powerful programs. The problem is not lack of FE-knowledge, but rather ignorance of plate behaviour. Therefore, the book starts with classical plate theory for membrane and bending states, and proceeds to FE-practice. The text can be used for university courses, acts as practical preparation for the engineering profession, and as a guide to structural designers.
