Scan-and-Solve for Rhino

Simulate Early, Simulate Often... In Rhino

Thanks for the webinar today. I enjoyed it. 

Michael, you quickly described how you would setup loads/forces in order to simulate an earthquake. I didn't quite catch it, but would really like to get further clarification on it.

Would you please expand on how 'body loads' are used in simulating earthquake scenarios?

Thanks,

Ernest

I think that Michael needs to rest after the webinar :-)     So let me answer.   Obviously,  you are not going to simulate a real earthquake with a linear static model of elasticity.    Proper simulation would require using (dynamic) accelerograms, modal (frequency) analysis, and so on.    But a poor man's version (used by many not-so-poor people) is an "equivalent static method",  where one assumes a peak ground acceleration in some direction and apply it as a static load on the structure.   For example,  one museum in an earthquake zone applies 0.7g  horizontally to their sculptures as a typical earthquake scenario.    In Scan&Solve,  you simply specify the direction and magnitude of the linear acceleration as explained in the documentation.

I see (guess I should have checked the documentation:).

Thanks for the quick response Vadim. Makes sense.

Cheers,

Ernest

Earthquake structureal strength is commonly done using static models according

to the building code.
