Behaviour and modelling of partial-strength beam-to-column composite joints for seismic applications. Braconi, A., Salvatore, W., Tremblay, R., & Bursi, O. Earthquake Engineering and Structural Dynamics, 36(1):142 - 161, 2007. Beam-to-column joints;Joint typology;Moment-resisting frames;
Paper abstract bibtex A refined component model is proposed to predict the inelastic monotonic response of exterior and interior beam-to-column joints for partial-strength composite steel-concrete moment-resisting frames. The joint typology is designed to exhibit ductile seismic response through plastic deformation developing simultaneously in the column web panel in shear, the bolted end-plate connection, the column flanges in bending and the steel reinforcing bars in tension. The model can handle the large inelastic deformations consistent with high ductility moment-resisting frames. Slip response between the concrete slab and the beams was taken into account. A fibre representation was adopted for the concrete slab to accurately capture the non-uniform stress distribution and progressive crushing of the concrete at the interface between the concrete slab and the column flange. The model is validated against results from full-scale subassemblages monotonic physical tests performed at the University of Pisa, Italy. A parametric study is presented to illustrate the capabilities of the model and the behaviour of the joints examined. Copyright © 2006 John Wiley & Sons, Ltd.
