This diagram shows the primary structural column element that was used on the Renault Centre. The details for the top, middle and tension connectors have been isolated below. The idea behind a system such as this is to enable mass replication of the connections, using a kit of parts that are custom fabricated off site, and bolted together on site. This makes for better economy and ensures that processes such as cutting and welding operations take place in controlled environments.

The detail at the top of the round HSS column must allow for the connection of 8 incoming tension rods. The HSS stub at the top is smaller than the column. there is enough space between each triangular plate fin to allow for welding of the plate to the stub as well as for the attaching of the clevis type connectors to which the tension rods are attached.

A round collar has been welded to the round HSS column, and to this, the plate fins to which a set of tensile connectors are attached. Again clevis type connectors are used to connect the tension rods to the column. The clevis allows for rotation of the pin type connection with assists in alignment during erection processes.

The custom fabricated beams are joined to the round HSS column using a larger variation of the collar in the above detail. Again there must be adequate space between the plates that are welded to the collar by which to attach the beams. Where the vertical tension connectors are attached to the beam, a round steel collar has been welded to the web cut out in order to reinforce the connection.
