Abstract
Recently researchers concentrate on alternative fuse designs promoting the concept of performance-based design while reducing the beam section in different ways including that of creating a hole in its web (RWS connections). Similar practice is applied in the fabrication of perforated beams mostly used to support the service integration as well as the significant mass reduction in steel frames. This paper presents a finite element (FE) analysis of a partially restrained extended end-plate connection with single and multiple circular web perforations introduced along the length of the beam and subjected to the cyclic loading proposed by SAC protocol from FEMA-350 (2000). The parameters introduced were the distance from the face of the column, S, and the number of closely spaced web openings. The design of such connections should be based on the articulate decision of the first opening’s distance from the face of the column.
