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

在本文中，对具有多个六角腹板开口的梁柱焊接连接进行了有限元 (FE) 分析。开口沿着梁的长度分布，梁的长度受到 SAC 和 FEMA 350 (2000) 提出的循环加载协议的影响。这项研究的重点是从柱子到穿孔梁的连接的相互作用和应力的移动。解决了两个参数：距柱面的距离 (S) 和腹板开口间距 (So)，包括紧密间隔的开口。研究表明，主要受控的减缩腹板截面 (RWS) 连接的设计应从根本上基于第一个开口与柱面的距离。显示了距离 (S) 的三个值（200 毫米、350 毫米和 520 毫米）。
