Study on Mechanical Performance of Prestressed UHPFRC U-Beam Bridges

Table 1

Actual loading values.

Load range of single loading point	Load unit	Note
0∼20 kN	2 kN	Limit bearing capacity of the one-way slab, observe initial cracks
20 kN∼50 kN	5 kN
50 kN∼60 kN	2 kN	Ultimate bearing capacity of the two-way slab, observe cracks
60 kN to END	Displacement control	The deformation increases while the load application does not grow
