Drej,
Ordinary loads and reactions can be combined using the SRSS method. But my question is whether the same procedure can be followed for a seismic analysis. I'm questioning this as all the test reports I've seen come with separate response curves for the 3 mutually perpendicular directions...
The earthquake inout is given at the fixed locations on the component. Say, the component that has to be tested for seismic compliance is bolted to a frame, the seismic input has to be given to the bolts, after giving a suitable constraint while doing the modal analysis. The seismic procedure...
Hi,
This is infact a question back to you. I have a similar problem now. I saw your question when I was searching for seismic analysis.
As far as I know it, the 3 directions are independent in terms of the response and has to be given as such. I've no knowledge of any combination of the 3...
