ACCURACY OF EVALUATIONS ON DEFORMATION CAPACITY OF STEEL BEAM-END CONNECTIONS

Abstract

Deformation capacity of steel beam-end connections has been evaluating based on methods proposed in correspondence with loading history, which was employed for the experiment. However, the relationship between the evaluation methods, and their accuracies have not been sufficiently investigated. In this study, an experimental database of steel beam-end connections subjected to constant amplitude cyclic loading, increasing incremental amplitude cyclic loading was established. Based on the experimental database, evaluation methods that are independent on loading histories and their accuracies were discussed. In addition, experimental results of beam-end connections carried out by the authors were used to verify the accuracy of the evaluation methods.
