| Abstract: | The members in bending can be strengthened by using prestressed high strength strands in continuous multi span folded pattern, tensile longitudinally at both ends and laterally at the beam bottom in the middle of span. It is a new technology for strengthening buildings. The typical engineering case presented in the paper explains the concept design and construction of this technology.[ |
