This is the reinforcement of the KTB external cables using corrosion-resistant PC steel materials that have obtained construction technology examination certification.
The external cable reinforcement method aims to improve bending and shear resistance by placing PC steel materials outside the member and applying tension through anchorage or deflection points. The KTB external cable reinforcement method uses PC steel materials that are particularly excellent in corrosion resistance and fatigue resistance, and employs SC unbonded or Ducst unbonded materials that are not subject to UV degradation.
