Introduction The crack width and deflection can be reduced effectively in civil engineering structure when it uses prestressed concrete (PSC) technique, because the compressive strength of concrete and tensile strength of steel bar in PSC can play their role effectively.
So PSC structure is widely used in civil engineering [1].
The training data will increase network availability especially large prestressed girder bridge field data collected in engineering practice.
