Moment-Rotation Response of 3D Beam-to-Column Joints with and Without the Slab
摘要
The most of existing numerical and experimental studies on seismic-resistant beam-to-column joints were carried out on 2D (i.e., planar) assemblies, thus disregarding the presence of the slab and the transverse beams that typically resist gravity loads in multistorey buildings. In this article, the influence of the slab and the transverse beams on the ultimate response of steel composite beam-to-column joints is investigated through finite element simulations. The results of the performed analyses show that these features may significantly affect the overall response of the beam-to-column assembly in the case of large rotations.
