When you work with cast-in-place concretecast unit type where the concrete is formed, poured, and cured in its final position
parts, it is important that you regularly check the resulting pour objects, and try to get rid of the errors related to them, before you start detailing, or creating drawings and reports. The errors in solid pour objects may lead to inaccuracies in volume and other quantity calculations, and to incorrect representationthe way that the information included in a model is represented visually
and hatching in drawings.
While you model, use the following methods to check the model for pour-related errors:
- Check if there are Solid error rows in the session history log file.
- Ensure that the cast-in-place concrete parts and pour objects look continuous in model views. They should not have part outlines or shadow lines inside them, like in the following images:
If you notice errors or overlapping volumes or faces, try remodeling some of the parts.
You can also try out the following tips to avoid pour-related errors:
- Make sure that the number of parts included in a single pour objectbuilding object that is formed of one or more cast-in-place concrete parts, or a part of a cast-in-place concrete part
The cast-in-place concrete parts are merged into one pour object if they have the same material grade and pour phase, and if they touch each other. Pour objects are visible in pour view.
- Sometimes modeling the parts in a different order may fix errors in pour objects.
- To control which lines are visible in drawings, use the advanced optionssettings used to customize Tekla Structures for specific companies, standards, users, or user groups
In Tekla Structures, advanced options are settings that are used, for example, in a specific project or geographical area, or by a specific company.
In Tekla Structures, advanced options usually begin with the initials XS and are followed by the name of the function, for example XS_BACKGROUND_COLOR.
XS_DRAW_CAST_PHASE_INTERNAL_LINES and XS_DRAW_CAST_UNIT_INTERNAL_LINES.
This may help because the cast-in-place concrete parts that have errors are treated in the same way in drawings as the precast concrete parts.
If remodeling the parts does not fix errors in solid pour objects, then overlap the parts as little as possible to ensure that the volume and quantity calculations are close to the correct values.
Example: Identify and fix a pour error
This is how an error related to a solid pour object can be indicated in a model viewview that is represented in the modeling mode
Model view is available also in the drawing mode and it is represented in its own window.
and in a drawing. The pour object is not shown as continuous, and there are extra lines between the parts in the pour object:
Checking the session history log file and clicking a Solid failure position row helps you to locate the error in the model (press Ctrl+2 to see through the parts):
Try moving a beam end so that it is no longer on the same surface as the column side:
This is how the model and the drawing look like after you have fixed the model:
Also the volume of the pour object is now correct, for example, in reports. The overlapping volume of the beam and the column is only counted once.
