Effects of Various Parameters on the Collapse Mechanism of Panels with Offset Beam-to-Column Connections of Steel Structures

通常情况下，标准的梁柱节点板通常采用标准的梁柱连接板，其中连接到柱上的左右两根梁具有相同的梁高和翼缘位置。然而，由于功能要求和减轻钢框架重量的目的，采用了柱两侧梁的梁高度和翼缘位置不同的连接方式。这样的面板被称为偏置面板。这些电池板展示了几种坍塌机制。本文提出了用弹性解析法计算各种坍塌机制形成过程中屈服强度的公式，并用参数计算检验了各种参数对板材屈服强度的影响。研究结果明确了在设计阶段将根据柱和板的截面形状来研究的倒塌机理。

In general, standard beam-to-column connection panels are commonly adopted in which both the right and left beams connected to a column share identical beam depth and flange position. However, due to functional requirements and with the aim of reducing the weight of the steel frame, connections were adopted in which the beams on either side of the columns have a different beam depth and flange position. Such panels are called offset panels. These panels exhibit several collapse mechanisms. In this paper, an equation is proposed that calculates yield strength during the formation of various collapse mechanisms based on the elastic analytical method, and at the same time an examination using parametric calculations is made of the effect of various parameters on panel yield strength. The research results thus obtained have clarified the collapse mechanisms to be examined at the design stage depending on the sectional configuration of the columns and panels.
