Removal of support or pier without jacks. Postensioned steel structure: Wedge-chock methodstatement; technology derivated

Abstract

The removal of supports is a common necessity when there is a change of architectural use or a span change in a bridge. The present document proposes a solution of easy technology that allows defining a procedure of cutting and bridging a support without the use of jacks. From this method statement arise a posttensioned technology for steel structure.
