Response Spectrum Eccentricity

[geodou]

Hello to all...Does anyone know where is the diaphragm eccentricity in the response spectrum case? In sap2000 v11 it was in the right side of the form... In sap2000 v14 i don't see it anywhere....

Thank you all in advance...

After defining earthquake load in Load Patterns, you click on Modify lateral Load Pattern to assign the eccentricity for all diaphragm.

Thanks miquan...So the modifications you do in eccentricity for diaphragms in the load patterns also effect eccentricities for the load cases (dynamic analysis)....
It is strange though because if you open the help and type eccentricities it describes the response spectrum form as it was in sap2000 v11...With eccentricities at the response spectrum form...
Anyway i will run a test model to see if changing the eccentricity in load patterns affect the load case...

Thanks again miquan....

Of course, you can using response spectrum to define seismic load.
At first, you fine a response spectrum function like that.



After that, you define seismic load as user define in define load patterns.



Final, define spectrum for this load.

hallo any body, I will try design a 3D flat-plate building with SAP2000, and I have any problem when defining the hinge properties for the plates so that the can be analyzed with phushover analysis. please help me. sorry my English is verry bad. thanks for all.
