Cyclic capacity of tubular beam-columns with local buckling: Numerical and experimental studies
Conference
·
OSTI ID:449697
The present investigation addresses the cyclic capacity of tubular members subjected to both local and global buckling during cyclic loading. Diameter to thickness ratios of 45 and 60 are studied. The performance of FE models, both a beam model and shell model, is compared to test results in terms of load versus displacement behavior and energy accumulation. Some problems regarding the prediction of local strain histories in the local buckle zone are pointed out. Damage accumulation models in terms of energy per cycle are discussed, aiming at possible member detachment criteria.
