Question:

Hi all,

one question about construction stage analysis on Midas FEA: does the geometric matrix is update from stage to stage?

thaks

regards



Answer:

Hi,

Geometric nonlinear analysis is not supported during the construction stage analysis. Only material nonlinear effects can be taken into account during the construction stage analysis.

Hi, yes I know that geometric nonlinear analysis is not supported during the construction stage analysis, I need another answer : does the geometric matrix is update from stage to stage?


thanks

Hi,

What do you mean by "Geometric matric"?

DK, I mean Geometric matrix... I mean KG, if shape of mesh, position of load are update from stage to stage



Hi,

Geometric stiffness matrix is only used for the geometric nonlinear analysis which is not supported in the construction stage analysis. Thus, geometric stiffness matrix is not generated in the construction stage analysis. It is not generated so it cannot be updated. This was what I meant in my previous reply. Do you mean something else?
