This disclosure relates to the field of
bridge engineering, specifically to a design method,
system, and medium for HPC-RC combined eccentrically compressed columns. The method includes: defining a
design space; selecting
optimal design data combinations based on
engineering specification constraints,
bearing capacity constraints, and cost-effectiveness values to construct a
design data sample set; constructing a two-
branch heterogeneous neural
network model, the model including an input layer, a shared
feature extraction layer, a
diameter prediction classification
branch, and a reinforcement area prediction regression
branch; constructing a
loss function composed of focal loss and
mean square error loss; training the two-branch heterogeneous neural
network model using the
design data sample set; and using the trained two-branch heterogeneous neural
network model to predict the
diameter and total reinforcement area of the eccentrically compressed column. This disclosure improves the stability and accuracy of the design, reduces the computational burden, increases computational speed, and reduces computational complexity.
