External post-tensioning, in which tendons are installed on the outside of a structural member with the aid of deviators and anchorages, is an attractive strengthening method as it does not add much weight …
WebThe use of external post-tensioning for new structural systems have been developed in the past decade. Under the PRESS (Precast Seismic Structural Systems), [11] a large-scale U.S./Japan joint research program, unbonded post-tensioning high strength steel tendons have been used to achieve a moment-resisting system that has self-centering capacity.
