UHPC Beams and U shaped girder

Dataset 1 include 100 rebar-reinforced rectangular UHPC beams data. The selection criteria for these datasets is stringent, including: (1) a minimum cubic compressive strength of UHPC of 110 MPa (16 ksi); (2) the use of three-point or four-point bending tests for flexural analysis; (3) the use of hot-rolled ribbed rebars for steel reinforcement; (4) a minimum steel fiber volume fraction of 0.5%; (5) balanced-reinforced failure of UHPC beams, ensuring neither over-reinforcement nor under-reinforcement (Balanced-reinforced failure indicates that the UHPC beam, with moderate steel reinforcements, simultaneously reaches both tensile and compressive limit strains upon failure). Whereas for Dataset 2, A computer algorithm has been developed using modified box complex method (63, 64). The algorithm works on the principle of replacing the worst design point with a new point called a reflecting point, which is found by reflecting the worst design point having maximum objective function through the centroid of the leftover design points in the complex [65], [66], [67]. During this process all the feasible design points are stored. There are nine independent features included in the dataset, specifically related to the geometrical configuration of U-shaped girders. The ultimate moment capacity of U-shaped girders is the dependent variable that serves as the output.
