Interpretable Optimization Design of Polygonal Pretensioned Concrete Bulb-T Girders Considering Tendon Section Coordination and Performance Cost Efficiency
Hongzhi Xu, Qingfei Gao, Bowen Ruan, Shuo Zhang et autres
The design of polygonal pretensioned concrete girders involves a practical conflict among load-carrying capacity, stiffness, ductility, damage control, and material cost. In conventional design, these characteristics are strongly coupled: increasing web thickness may improve stiffness but reduce ductility, while modifying tendon inclination …
