Abstract：Since the 19th century, the Industrial Revolution promoted more complicated architectural engineering, and structural design and calculation were no longer the responsibilities of architects. Since then, architects have relied on a limited number of structural types, which has restricted the coherence, flexibility and innovation of their design thinking. To break free from the constraints of these structural types and gain a deeper understanding of the relationships between them, this study starts with the hypothetical model of section forces of a simply supported beam. It simplifies the internal forces of the beam to the normal stress of the bending moment. Aiming to increase the ratio of the beam span to the structural self-weight, the study employs research methods such as quantitative reasoning, physical experiments, software simulations and case studies. It qualitatively analyzes the structural performance-based deduction processes of stress, load, beam height, and beam width. Ultimately, it reveals the logic-driven thinking behind the evolution patterns and the positive role of digital technology in more efficiently allocating materials.
