Bursting force in post-tensioned concrete I beam
https://orcid.org/http://orcid.org/0000-0002-8721-6773
In this study, anchorage zone stresses were studied in post-tensioned prestressed concrete I-section beam using three-dimensional (3D) finite element analysis for static loading condition with various load configurations like concentric and eccentric post-tensioning loads. The influence of important parameter like anchorage ratio, eccentricity and size of anchorage plate were studied. A three-dimensional problem was formulated. Effect of eccentricity, size of anchorage plate and various widths to depth ratio over the bursting tensile force developed in the anchorage zone is studied and an equation is presented to compute the magnitude of bursting tensile force by incorporating the effect of these parameters. The validation of model was done by comparing experimental results with computational result calculated using developed equation. From the study, it is observed that there is transverse tensile stress and bursting tensile force is inversely proportional to the eccentricity, size of anchorage plate and t/D ratio. Also, it is observed that bursting tensile force is calculated by incorporating these variables are higher than force calculated by IS-1343:2000.
