| 摘要： | Abstract Though topology optimization has been around for nearly 3 decades, its application in the design of RC structures still is a concern, not only because of the lack of a definite procedure, but also because of the lack of supporting and reassuring experimental evidence. This paper presents a practical integration of topology optimization to the design of RC beams with experimental validation. Concrete and steel reinforcement profiles based on two-material topology optimization were considered as a form suggestion and used for design guidance. The design was refined constantly to alleviate any stress and deflection violations, and the beam successively evolved. A supporting experiment verified that a reduction of approximately 30% in concrete can be achieved while all the relevant design requirements remained satisfied and integrity was maintained, with more than 3 times the beam’s service capacity reserved. |
