The definitive work on structural systems - clear, visual, timeless Structure Systems by Heino Engel has been regarded as a definitive standard work on the typology of structural systems in architecture since its first publication in 1997. Clear, accessible, and visually striking, it illustrates the interplay between structure and form-without technical overload. Focusing on archetypal structural systems, this bilingual edition (German and English) offers a visual grammar of structural forms, making it ideal for education, design, and inspiration. With over 500 outstanding drawings and model photographs, a systematic presentation of the most important structural types, and numerous impulses for creative design approaches in architecture and engineering, the book convinces both visually and conceptually. Proven for over 25 years. A work that unites tradition, opens up creative freedom, and serves as a visual toolbox.
