ABSTRACT:
Advantageously, the present invention also facilitates a unique method for post-tensioning segmental viaduct structures, for rapid transit use or otherwise, wherein post-tensioning cables do not follow load diagrams but instead follow uniform paths through each viaduct segment. In this way, each viaduct segment need not be specially fabricated to accommodate uniquely positioned cables.
