Parametric study of reduced web section of beam to column welded connection with castellated beam having hexagonal openings and subjected to cyclic loading

Abstract In this paper, a finite element (FE) analysis is carried out on beam to column welded connections with multiple hexagonal web openings. The openings are distributed along the length of which subjected cyclic loading protocol proposed by SAC and FEMA 350 (2000). This study focuses interaction from columns perforated mobilization stresses. Two parameters were addressed: distance face (S), opening spacing (So) including closely spaced opening. revealed that design mostly controlled reduced section (RWS) should be fundamentally based first column. Three values (S) presented (200 mm, 350mm, 520 mm). A model an ideal mm has resulted in ultimate rotation 0.039649 rad, less than other models, rotations 0.049386 rad 0.050000 respectively.
