Following an introductory discussion of the implications of external prestressing for rehabilitated structures, their analysis and design, this paper provides a brief summary of a newly developed rational yet simplified methodology which allows for the evaluation of the moment curvature response as well as the stresses along critical sections, of members prestressed or partially prestressed with external tendons so as to allow the evaluation Cited by: 3. This paper adopted an innovative external prestressing method to study the flexural behavior of externally prestressed CFRP (Carbon Fibre Reinforced Plastic) tendons strengthened T . A parametric study was carried out to investigate the effect of different external tendon layouts and different levels of torsion. Keywords: Combined load, externally prestressed, segmented concrete bridge, . external prestressing of concrete tively. EXTERNAL PRESTRESSING External prestressing refers to a post-tensioning method in which tendons are placed on the outside of a structural member. This technique is adopted in bridges and strengthening of buildings. It is an attractive method.
Ultimate Flexural Behaviour of Externally Prestressed New Beams and Journal of Engineering Science and Technology April , Vol. 10(4) concerned, external prestressing is one of the major strengthening techniques, being applied for distressed concrete bridges. Apart from bridge field, it File Size: KB. Currently, segmental box girder bridges with external prestressing is widely used in construction all over the world. This paper presents experimental test results on five specimens represents a. remarkable use of external prestressing in bridges. Because external prestressing system is simpler to construct and easier to inspect and maintain as compared with the internal tendon system, it has been proposed recently in the construction of segmental bridges (4, 5) as well. Some of the recent application of external prestressing in the new bridges is briefly discussed in the following by: 6.

differences that results from the choice of a solution with internal or external prestressing. A comparative study was performed on two realistic models of a five spans continuous single-cell box girder: one with internal and the other with external prestressing. The parameters investigated are the bridge span and the depth of the girder. the principles of external post-tensioning, the conclusions of the laboratory studies, and presents the full scale strengthening of two bridges, Condet bridge in Jakarta, and Kemlaka Gede bridge near Cirebon, are presented as case studies.
