Description
Summary:This report presents a load combination methodology for dynamic response analysis problems, based on a stochastic approach which has been introduced in the field of random vibration theory. The methodology proposed has the advantage that the appropriate correlation effect among combined load components is considered and is evaluated in terms of the dynamic correlation factor. The specific combination problem discussed in this paper is the calculation of the maximum base shear coefficient of a large-scale cylindrical liquid storage tank which can be simulated by a simplified lumped-mass model, neglecting the sloshing effect. The accuracy of this method is statistically examined by use of the random vibration technique; and its advantage over the square root of the sum of the squares law and the absolute value summation law is examined using numerical examples.
