Title: Beam Bar Anchorage in Exterior Column-Beam Connections
Author(s): T. Ueda, I. Lin, and N. M. Hawkins
Publication: Journal Proceedings
Appears on pages(s): 412-422
Keywords: anchorage (structural); beams (supports); bond (concrete to reinforcement);
columns (supports); computer programs; connections; embedment.
Abstract:The development of a computer model that can predict the load-lead end deformation and anchorage length requirements for reinforcing bars extending from beams into exterior columns and subjected to large inelastic loadings is reported. The model incorporates six basic elements: a local bond stress-slip relationship; a stress-strain relationship for the steel; a continuity condition between steel and concrete; a modification for unconfined concrete; a failure criterion; and an equivalent embedment length criterion for a hooked bar. The results of the model are shown to be in good agreement with the results of tests on straight and 90 deg hooked bars anchored within specimens simulating conditions for exterior column-beam connections.
