One of the disadvantages of building with tubular structures lies in executing rigid or semi-rigid joints. Up to date, the most reliable way to solve these joints is by welding; this would not be a problem if the entire welding could be done at workshop, since the available precision is much higher than in the worksite. In order to solve this problem, a new high-rise solution is proposed and analyzed in this study. The proposal is based on inserting one tube into a wider one (working as a bracket, and previously welded to the column at the workshop). Then, the proposed joint works thanks to the assemblage between the tubes, by making profit of the geometry itself. Of course the tolerance of the tubular profiles is a decisive point; for that purpose, a fine injected mortar layer is also proposed in order to fill the existing gap between them. © 2013 Taylor & Francis Group.
