Designing Efficient Welds to Branch Plates

为了更有效地设计焊接件，已经为许多矩形空心截面的连接建立了焊缝有效长度方程。这种方程也已被开发为一个小数目的连接到/之间的圆形空心部分（CHS）。从长远来看，需要研究来扩展这些规则。目前的建议是进行研究，以确定：（a）单面焊接的影响;（B）偏心荷载的影响;（c）板对板和板对CHST、Y和X连接中分支板的焊接有效长度。预计这项工作将导致新的设计规则的实施到即将修订的设计规范，将减少材料，劳动力和详细的要求钢连接。

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.
