| description | Theaim of this paper is to examine the effect of strand configuration on stressdistribution and debonding parameters of precast, pretensioned concrete girdersafter prestressing force is transferred from strands to concrete by bond attheir interface. Determination of strand configuration is important as well asdetermination of number of strands because it affects stress distribution anddebonding parameters of girders. The debonding of strands is an application inorder to control the tensile and compressive stresses at the support zone ofgirder. One of the typical precast girder with 90 cm height is considered inthis study. To determine the effect of strand configuration, nine girders withthe same cross-section, effective span length and material properties butdifferent strand configuration are selected as an application. Equalprestressing force is applied all strands simultaneously. Three dimensionalfinite element models (FEM) of girder are constituted using SAP 2000 software.At the end of the study, numerically identified stress distribution andcalculated debonding parameters of girders compared with each other. |
