Digital manufacturing has transformed many industries but has had only a limited impact in the construction sector. To capitalize on advanced manufacturing techniques, this paper introduces a radically new connection approach for gravity structural steel frames. The proposed intermeshed steel connection (ISC) exploits robotic abilities to cut structural steel member ends precisely to accelerate deployment and offer better disassembly options over existing approaches. Forces are transferred through common bearing surfaces at multiple contact points, and connections can be secured by small locking pieces. This paper introduces the geometry, manufacturing, and initial analysis and test results of the connection. The paper demonstrates the ability of the connection to (1) be manufactured within current industrial tolerances, (2) be erected and disassembled, and (3) perform at expected design levels.

<p>Three-dimensional intermeshing of steel enabled by advanced digital manufacturing holds the potential to radically change how steel bridges and buildings are connected. This paper presents the concept of the first universal structural steel connection in over 100 years. The proposed Intermeshed Steel Connection (ISC) exploits recent advances in steel cutting technologies and robotics to shape member ends precisely. This vastly reduces on-site bolting and welding. Forces are transferred through common bearing surfaces at multiple contact points. The new connection is designed to accelerate structural steel deployment and offer better disassembly options. This paper introduces the geometry, manufacturing, and initial analysis of the connection approach, which holds the potential to be robust, secure, scalable, and faster to erect.</p>

O estudo se desenvolveu por meio da fabricação e posterior ensaio de corpos de prova confeccionados por meio de Direct Digital Manufacturing (DDM), usinagem de placas extrudadas e injeção de polímeros. Um comparativo das propriedades mecânicas obtidas pelos ensaios de tração foi realizada. A avaliação das aplicações de peças DDM, especialmente por se tratar de uma tecnologia relativamente jovem e que ainda não tem todo seu potencial explorado, foi o que motivou a realização desse trabalho. Cada um dos três processos avaliados apresentou particularidades. Os ensaios de peças usinadas e injetadas apresentaram resultados bem característicos, sendo o material usinado mais resistivo à forças trativas do que o material injetado. As peças fabricadas por DDM se mostraram tão eficientes quanto à injeção no ensaio de tração.
