- W2186975980 abstract "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 the post-tensioned member with grouting void. Parametric analysis 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. or at great cost. In order to evaluate the effect of grouting void on the PC tendon stress in post-tensioned PC member, a nonlinear analytical method is devised considering the concept of member's strain compatibility in the region of un-grouted tendon for the calculation of the tendon stress in the ultimate state. In addition, elastic analytical methods for those in un-cracked and cracked states are also discussed. The parameters investigated include void-span ratio, load application type, PC tendon profile and partial prestressing ratio (PPR=fpyAps/(fpyAps+fyAs)). Based on the grouting mechanism (3), the analysis is conducted on simply supported member by gradually increasing the total void's length from mid-span to supports symmetrically. Results of parametric analysis indicate that the strain reduction coefficient of PC tendon is very sensitive to the void-span ratio while the loss of ultimate stress and moment capacity are not if failure mode is controlled by the crush of concrete. These phenomena imply that repair or strengthening is not necessary even if the voids are existed in members on condition that a reliable corrosion protection is provided for PC tendons and consequently no risk of tendon rupture will happen. Before describing the nonlinear analytical method for the ultimate state and presenting the results of this investigation, strain reduction coefficient of PC tendon in elastic cracked or un-cracked state is introduced next." @default.
