Multiple Base Excitation in SAP2000
Multiple Base Excitation in SAP2000
(OP)
SAP2000 version 10.0 (Advanced) denotes that 'Multiple Base Excitation' (that is different acceleration at each support) is feasible. However, I cannot find any information on how to define it. Has anyone used this feature?
Many thanks.
Many thanks.





RE: Multiple Base Excitation in SAP2000
Also, you can assign different imposed joint displacements at each support which also opens the possibility of applying time history functions to these displacements.
Both suggestions are admittedly different than using different accelerations at each support, but they may help you get to where you want to go. Let us know if you come up with anything more.
