Description |
Use for |
---|---|---|
Neutral axis |
The neutral axis is the analysis axis for this part. The location of the analysis axis changes if the profile of the part changes. |
|
Reference axis (eccentricity by neutral axis) |
The part reference line is the analysis axis for this part. The location of the neutral axis defines the axis eccentricity. |
|
Reference axis |
The part reference line is the analysis axis for this part. |
|
Top left |
The analysis axis is located in the top left corner of the part. |
Beam objects (beams, columns, braces) |
Top center |
The analysis axis is located in the top center point of the part cross section. |
Beam objects |
Top right |
The analysis axis is located in the top right corner of the part. |
Beam objects |
Middle left |
The analysis axis is located in the middle of the left side of the part. |
Beam objects |
Middle center |
The analysis axis is located in the center point of the part cross section. |
Beam objects |
Middle right |
The analysis axis is located in the middle of the right side of the part. |
Beam objects |
Bottom left |
The analysis axis is located in the bottom left corner of the part. |
Beam objects |
Bottom center |
The analysis axis is located in the bottom center point of the part cross section. |
Beam objects |
Bottom right |
The analysis axis is located in the bottom right corner of the part. |
Beam objects |
Top plane |
The analysis axis is bound to the top plane. |
Plate objects (plates, slabs, panels) |
Middle plane |
The analysis axis is bound to the middle plane. |
Plate objects |
Bottom plane |
The analysis axis is bound to the bottom plane. |
Plate objects |
Left plane |
The analysis axis is bound to the left plane. |
Plate objects |
Right plane |
The analysis axis is bound to the right plane. |
Plate objects |
Middle plane (of left/right) |
The analysis axis is bound to the middle plane of left/right. |
Plate objects |
Tekla Structures uses the options above for each part when you select Model default from the Member axis location list in the Analysis Model Properties dialog box.
If you select Neutral axis, Tekla Structures takes the part location and end offsets into account when it creates nodes. If you select either of the Reference axis options, Tekla Structures creates nodes at part reference points.
You can also use keyboard shortcuts to move the selected analysis part in relation to the physical part.
