Owing to the complex construction of continuous girder bridges,which is laboursome and time-consuming,people have been thinking about an approach to combining the advantages of the two so as to speed up the building and reduce the work procedures. Thus the "simply-supported-continuous system" is introduced.

但是由于现浇连续梁的施工复杂繁琐、费工费时，人们一直希望将简支梁的批量预制生产和连续梁的优越性能结合起来，用梁或板批量预制生产的方式来加快连续梁的建设速度，以省去繁琐的支模工序，由此产生了将整跨梁板预制、架设就位后在端部浇筑混凝土并张拉预应力使之连续的&先简支后连续&施工法，而形成的体系则被称为&先简支后连续结构体系&。
