Measures may be taken to improve the accuracy of output acceleration generated during time-history analysis. This article provides guidelines for these measures, which involve damping, inertia, output time step, and possible Hilber-Hughes-Taylor alpha-method application. |
Measures should be taken to obtain accurate output acceleration from time-history analysis. Acceleration is the second derivative of displacement, and derivative values are less accurate than integrated quantities during numerical analysis.
