Size effect in anchorage behavior

Abstract

The results of the numerical analysis for pull-out tests on headed anchors with axis-symmetric finite elements and nonlocal microplane model for concrete are presented. Based on the results of the numerical analysis and Bazant's size effect law a failure load formula is derived and compared with empirical failure load equations. Numerical results are in good agreement with experimental evidence and indicate a strong size effect which should be taken into account in current design practice.
