Conceptual Transparency: Examples from the Work of Robert Maillart and Jörg Schlaich

Design processes and design calculations are reviewed for the 1925 Valtschielbach Bridge by Robert Maillart and the 1998 Ingolstadt Bridge by Jörg and Michael Schlaich. This review emphasizes the importance of conceptual transparency in structural design and demonstrates the interconnected nature of theory and practice in actual design processes. It helps to establish engineering thinking as distinct from scientific or mathematical thinking, and allows detailed consideration of how structural design processes may be taught in the university. Examples from the author's own practice and teaching demonstrate the potential for learning environments where university students are introduced to the tools and disciplines essential to creating original work based on fundamental understanding of engineering concepts.
