Root Mean Square Acceleration (RMSA) is a statistical measure used to quantify the magnitude of acceleration signals over time, particularly in dynamic systems like tall buildings subjected to wind-induced vibrations. By calculating the square root of the average of the squares of the acceleration values, this metric helps in assessing structural responses and ensuring safety against oscillations caused by environmental factors. It provides insights into the structural integrity and comfort levels for occupants in tall structures during windy conditions.
