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。这种方程也适用于连接到圆形空心截面(CHS)的少量连接或连接在这些连接之间的连接。从长远来看，需要研究来推广这些规则。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；(C)板与板以及板与CHST、Y和X连接中分支板的焊接有效长度。预计这项工作将产生新的实施设计规则，并纳入即将修订的设计规范，以减少对钢连接的材料、劳动力和细节要求。

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.
