Designing Efficient Welds to Branch Plates

为了更有效地设计焊接件，已经建立了许多与钢矩形空心截面连接的焊缝有效长度方程。这种方程也被用于与圆空心截面（CHS）之间的少量连接。从长远来看，需要进行研究以扩大这些规则。目前的建议是研究确定：(a)单面焊接的影响；(b)偏心加载的影响；(c)在板对板和板对chst， Y型和x型连接中分支板的有效焊接长度。预计这项工作将导致新的设计规则在即将修订的设计规范中实施，这将减少钢连接的材料、人工和详细要求。

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 numberof connections to/between circular hollow sections (CHS). Over the long-term, research is needed to expandthese rules. The current proposal is for research to determine: (a) the effect of single-sided welding; (b) theeffect of eccentric loading; and (c) weld effective lengths for branch plates in plate-to-plate and plate-to-CHST-, Y- and X-connections. It is anticipated that this work will result in new design rules for implementationinto forthcoming revisions of design codes that will reduce material, labor, and detailing requirements for steelconnections.
