A traditional frame analysis of the complete structure is always the first analysis that Tekla Structural Designerperforms in any combined analysis and design. This analysis generates a first set of results for the design of beams, columns and walls.
First Order or Second Order Analysis?
You can control whether a first, or a second order 3D Analysis is run by making the appropriate selection on the Analysis page of the Design Options dialog. The actual options that are presented will vary depending on the design code being worked to.
Linear or Non Linear Analysis?
The choice of linear or non-linear analysis is made automatically:
if the model has entirely linear properties a linear analysis is performed,
else if any non-linear properties are detected a non-linear analysis is performed.
