Connection Definition

Use this option to select the connection type and specify its parameters.

Access the option from the Connections layout or after clicking on the toolbar.

The screen is divided into 2 basic parts: the Inspector pane used for management of defined connections and the graphical viewer, which consists of several tabs:

• Scheme (a schematic drawing of a connection)
• 3D View (the view of a defined connection with a possibility of rotation, zoom, pan)
• Structure (the view of a whole structure)
• Results (a calculation note with results of connection calculations; available only after performing calculations).

The following connection types are available in Robot by clicking (New Connection):

• beam-beam connection
• frame knee connection
• column-beam connection
• column-beam (two-sided) connection
• column base - column connection: fixed
• column base - column connection: pinned
• column base - column connection: concrete base
• beam splice connection
• column splice connection
• , , , - angle connection
• pipe connection.
• , , - connection with a gusset plate: for a single bar, internal node, and truss chord node.

The following parameters can be defined for subsequent connection types:

• frame knee, beam-beam, and column-beam connection (table designation: KNEE):
  • bar section parameters
  • base parameters
  • stiffener parameters
  • anchorage parameters
  • concrete, weld and wedge parameters
• column-base connection (table designations: fixed base - FIX, pinned base - PINN, concrete base - CONC):
  • bar section parameters
  • reinforcement parameters
  • screw parameters
  • stiffener and plate parameters
  • depth of concrete base
• angle connection (table designation: ANG):
  • bar section parameters
  • angle parameters
  • bolt parameters
  • cut dimensions, distances, etc.
• pipe connection (table designation: PIP):
  • connection type (unilateral, bilateral)
  • parameters of adjoining bars (crosses)
  • bracket parameters
  • weld parameters
• connection - gusset (table designation: BLA):
  • connection type (welded, bolted) and its parameters
  • bar parameters etc.

Note: If a connection is defined, you can click (Connection Type Change) to change the type of connection:

• change to a pinned support
• change to a fixed support
• change to concrete support
• change to beam-to-beam connection
• change to frame knee connection
• change to beam-to-column connection
• change to column-beam (two-sided) connection
• change to beam splice connection
• change to column splice connection
• change to angle connection
• change to pipe connection
• change to connection with a gusset plate (single bar)
• change to connection with a gusset plate (internal node)
• change to connection with a gusset plate (truss chord node)

You can save a defined and calculated connection to a file of the following formats:

• DXF
• DWG
• STP
• WRL
• ANF
• SAT
• PEP
