默认 distortion of pre-fabd bridge components

distortion of pre-fab'd bridge components
i am interested in finding some data on how common distortion due to stress relieving activity takes place during transports of pre-fab'd bridge or other large structural components. i am especially interested in structures made out of some of the newer high performance steels.
