摘要：
In order to study further the resistance and rotation capacity of beam-column connections made of stain-steel S31608, this paper presents the experimental results of connection details under monotonic loading. stainless-steel bolts A4-80 and bearing connection instead of friction type connection are adopted for beam-column connections to improve connection form. An efficient and accuracy FEM model is proposed for numerical simulation under monotonic loading based on the material stress-strain relationship of stain-steel structure and bole A4-80. The connection strength and stress concentration at the end of the weld access hole and the root and the longitudinal direction of the wing plate of a connection are analyzed and compared between the connections. The comparison between FEA results and experimental data shows that the maximum bearing capacity is 251.6 kN and 246.3 kN, and that the maximum displacement is 197.9mm and 196.1mm respectively. Thusly, the nonlinear FEA method is satisfactory in simulating the behavior of bolt connections under monotonic loading and utilizable for later parameter analysis appropriately. © 2019, Engineering Mechanics Press.
