PROBLEM TO BE SOLVED: To enhance workability of arrangement of a reinforcing bar while increasing horizontal shearing strength of a joint between a corrugated steel web and an upper or lower concrete floor slab, in a PC bridge using corrugated steel for a web. SOLUTION: The PC bridge is composed of the upper and lower concrete floor slabs 1 and 2, and the corrugated steel web 3 for connecting both the floor slabs 1 and 2 together; web plates 5 are joined to flange plates 4 joined to end surfaces, on the sides of the floor slabs 1 and 2, of the web 3; the reinforcing bar 6, which is arranged in the floor slab 1 (2), penetrates at least either of the upper and lower web plates 5; and a groove 51, whose width on the side of an end surface 50 is as large as/larger than a diameter of the reinforcing bar 6 and whose depth is as large as/larger than the diameter of the reinforcing bar 6, is formed in such a manner as to continue from the end surface 50, on the other side of the flange plate 4, of at least either of the web plates 5 penetrated by the reinforcing bar 6 to the position of the arrangement of the reinforcing bar 6.
