Answer:
Yes it can be done.
With the model opened in AutoPIPE and the "Response/Force Spectrum Loads" displayed enter in the following data:
Next is the Spectrum data; entered in as pairs. These pairs contain data corresponding to Frequency/Period and A/G/F/V values.
Open an MS Excel spread sheet that contains 2 columns with the data in the correct units.
Select the 2 columns and all the rows containing the data pairs, right click the mouse button, choose Copy command from the listing
Back inside of AutoPIPE place the mouse pointer in the first "Data Type" cell, Right click the mouse button again and select PASTE, shown below:
Presto, all the data should now have been pasted into the dialog, shown below:
Note: Perform random spot checks to be sure all the data was correctly copied into the dialog.
A response spectrum analysis is used to determine the response of a structural system subjected to earthquake excitation. A response spectrum analysis uses results from the modal analysis to obtain a solution. Thus, a modal analysis must be performed before a response spectrum analysis is initiated. All assumptions made during the modal analysis apply.
Note: Only the AutoPIPE Advanced and Nuclear versions will allow specification of fifty response spectrum cases. The standard version of AutoPIPE will allow a maximum of five response spectrum cases.
Run a Response Spectrum analysis based on the parameters defined in the following locations:
Spectrum data (*.SPC) from the Response / Force Spectrum Load dialog
Modal TAB of the Dynamic Analysis dialog
Response Spectrum TAB of the Dynamic Analysis dialog
Sam analysis dialog (optional)
SAM / MRSRS Suport Group dialog (optional)
A detailed description of performing a MSRS analysis can be found in the following document:
C:\ Bentley\ AutoPIPE V8i SELECTseries\ Documents \ AutoPIPE_MSRS_Example1.pdf
(or try searching your hard drive for the file AutoPIPE_MSRS_Example1.pdf)
Note: this documented procedure can be adapted to perform a single response spectrum.
