Wind simulation using Robot Millennium




Robot Millennium now offers a wind simulation, but you still need to do one more step to get the final surface wind pressure. This video shows the dynamic wind pressure before multiplying by the size effect factor Ca and Cp and the code used over here is the British Standard.

Importing a model from AutoCAD to Etabs

Although the preferred method for modelling in Etabs is by using the grid and geometry wizard by Etabs for several reasons:

  1. Error and warning free model,
  2. Fast running,
  3. Accuracy.

However, sometimes we see very complicated structures with round floor plans, etc. so importing the model from AutoCAD would be easier. But, this will result in hundreds of warnings and sometimes error when running the model in Etabs and the model will likely take a long time to run.

There is a good practice where you can import the model from AutoCAD to Etabs and avoid these issues, by editing the exported points from Etabs in Excel.

Go through the points that have a long precision xx.056524 "For example" and reduce the number of digits and merge them as appropriate, then import the model to Etabs and test.

The maximum length of basement wall placed in rigid foundation?

As a continuous external restraint, the basement wall should have a reasonable length for concreting to control crack due to the temperature drop and shrinkage. What is the method for estimating the proper length without using reinforcement?
