This standard specifies the static load bending test methods and evaluation standards for simply supported prestressed concrete railway bridge beams that are fully prestressed, allow limited tensile stress, and allow cracks but limited crack width. This standard is applicable to T-shaped and box-shaped simply supported beams designed according to standard track gauge, factory (field) made post-tensioning, pre-tensioning method, and other simply supported beams can be used as a reference.
