Hi All
I want to simulate an ambient vibration to be used as an input to a Numerical Model. I want this to represent the vibrations occurred to the building through the wind, vehicle/human movement, etc.
The sole purpose of simulating this ambient vibration is to input it to the numerical model in order to find out the natural frequencies, mode shapes and damping ratios of the building through Operational Modal Analysis
Thank you
Hi Navindra,
More info regarding your system would be beneficial to suggest best option. You would need to implement those vibration either as force controled or displacement controled boundary conditions.

HI Romik Khajehtourian
I plan to implement the vibration as a displacement controlled. My plan is to input this motion as an acceleration to the building in order to simulate ambient vibration to the building.
Thereafter I plan to take the acceleration of the response of the building to move forward with the operational modal Analysis
Thank you
Navindra
Dear Navindra,
If you are using some kind of software for this simulation, you could do something like this Chapter Impact Force Localization Using Eigenfrequency Measurement i...
I have used simulation of the impact force, but you could do the same with wind and traffic excitation.
Only problem is that you have to describe how this acceleration is created. Wind and traffic are mostly random vibrations.
