要旨 Extensive investigation shows that deterioration due to insufficient grouting is a serious problem in post-tensioned concrete bridges which may have a detrimental effect on the load carrying capacity and durability of such structures. This paper presents an analytical method to evaluate ultimate tendon stress in post-tentioned member with grouting void. Parametric analytical is carried out to study the effects of the void-span ratio on strain reduction coefficient, ultimate tendon stress and bending moment with various tendon profiles, load geometry patterns and partial prestressing ratios.
