Use the Code Parameters tab to define parameters that are required by a selected steel code.
Note: The tab is available for Autodesk Robot Structural Analysis. It is not available for Autodesk Revit Structure.
The options available on this tab depend on the code selected in the Job Preferences dialog.
Eurocode 1993-1-8:2005
The options on the Code parameters tab are used to define the following code parameters:
- Column length
- Enter a default theoretical length of the connected element.
- Frame type
- Select a sway or non-sway frame.
- Anchors
- Enter a resistance reduction coefficient for anchors as specified in Table 3.4.2 .
- Concrete
- Select if the concrete is cracked or non-cracked.
- Grout layer
- Specify the characteristic strength and the coefficient of friction between the grout layer and the base plate.
- CEB analysis - Design Guide - "Design of fastenings in concrete" (1997)
- Enables or disables the analysis of sheared and tensioned anchors according to the CEB Design Guide.
- Select the types of analyses that you want to perform on the connection calculations.
Note: By default, all types of analyses are selected.
Available tension analyses
- Steel failure
- Pull-out failure
- Concrete cone failure
- Splitting failure
Available shear analyses
- Steel failure
- Shear load with lever arm
- Concrete pry-out failure
- Concrete edge failure
CM66
The options on the Code parameters tab are used to define the following code parameters:
- Method for calculation of the coefficient of bearing pressure onto concrete
- Select either the Lescuarch's method or the B.A.E.L method.
- Calculation of the K coefficient (bearing pressure onto concrete)
- You can select a default coefficient value, enter a coefficient, or let the program calculate a coefficient for you.
- Coefficient steel-concrete
- Enter a steel / concrete ratio, or let the program calculate it automatically.
PN-90/B-03200
The options on the Code parameters tab are used to define the following code parameters:
- Column end
- Specify if the column end is milled or not milled.
Note: The capacity of the connection in compression is specified as follows: it is assumed that 25% of the compressive force is carried by welds, while 75% by bearing pressure of the column section; the column pier should be machine cut or milled. If the pier face is not milled, it is assumed that welds carry 75% of the compressive force in the column. For connections in tension, the welds connecting the column pier with the base plate carry the whole force.
- Calculation model of the column base (fixed column base only)
- Select the plastic model [5.2.4 - for a user-defined load], or the elastic model [5.2.5 - for compression and bending].
