Designing Efficient Welds to Branch Plates

为了更有效地设计焊接件，已为许多钢矩形空心截面的连接建立了焊接有效长度公式。这样的方程也已经为少数人开发出来了。 连接到圆形空心截面(CHS)或连接到圆形空心截面(CHS)之间。从长远来看，需要扩大研究范围 这些规则。目前的建议是进行研究，以确定：(A)单面焊接的影响；(B) 偏心加载的影响；以及(C)板到板和板到管件中分支板的焊接有效长度 T形、Y形和X形连接。预计这项工作将产生新的实施设计规则 即将修订的设计规范，将减少对钢的材料、劳动力和细节要求 关系。

Weld effective length equations have been developed for many connections to steel rectangular hollow sections to allow for more efficient design of weldments. Such equations have also been developed for a small number of connections to/between circular hollow sections (CHS). Over the long-term, research is needed to expand these rules. The current proposal is for research to determine: (a) the effect of single-sided welding; (b) the effect of eccentric loading; and (c) weld effective lengths for branch plates in plate-to-plate and plate-to-CHS T-, Y- and X-connections. It is anticipated that this work will result in new design rules for implementation into forthcoming revisions of design codes that will reduce material, labor, and detailing requirements for steel connections.
