ABSTRACT:

The strength performance of three joints with T-section concrete filled steel tubular columns and I-section steel beams, one of which is all-welded joint and the other two are joints with welded flanges and bolted webs, are studied in this paper. Hysteretic curves and skeleton curves are acquired from experiments. Besides, deformation behaviors, reduction of strength performance and energy-dissipation capacity are analyzed. Results show that these joints have good hysteretic performance and energy-dissipation capacity. The quality of welding between beams and sleeves and plug welding between sleeves and columns has great impact on the strength performance of joints, as well as deformation behaviors and energy-dissipation capacity. The number of plug welding influences strength performance, while the quality of welding influences energy-dissipation capacity. Finite element models are established. Results of finite element analysis show good agreement with experimental results, which indicates that these finite element models can be used for parameters analysis.
