Abstract

Abstract

For analysis of serviceability behavior of reinforced concrete beams strengthened with external tendons,external prestressing effects can be modeled as equivalent loads varying with imposed external loads.Formulas of stress increments of external tendons were proposed for serviceability state based on those for capacity ultimate state,and thus current deflection calculation methods can be used.
- external prestressing,
- strengthening,
- deflection control
