I have an Autopipe model I would like to carry out Earthquake and Dynamic analysis with SAMs.
I have applied the static Earthquake case as shown below as an initial check.
I have also applied the response spectrum,(see below) adding support groups with corresponding imposed displacements (see R1, SAM case 1 example)
Response spectrum analysis window
Case 1 definition window
Do the R1, R2… results, automatically combine the response spectrum analysis with the imposed displacements applied in S1,S2…?
Or do I still need to create a user define load combination to capture the response spectrum and the corresponding imposed displacements?
If so please could you elaborate on the combination I need to implement, providing an example for R1S1?
Thank you for your help.
You have not said what code you are designing too. B31E 3.4 is clear that you add the R and S. But B31E also has high allowable stress.
I am using the EN13480 code
