Modeling and parametric study of Cover Plate strengthen- beam flange weaken beam-to-column connection for steel moment frame

摘要

Based on the previous experiments and theoretical analyses, finite element analyses (FEA) and parametric study on seismic behavior of Cover Plate Strengthen-Beam Flange Weaken Beam-to-Column (CPSBFW) connection are executed by using ABAQUS. Suggestions on design conceptions and details of the cover plate strengthen-beam flange weaken beam-to-column connection are presented in this paper, and that provide valuable reference for design of beam-to-column connections in steel structures.
