This paper is an extended study of a practical combination method of dynamic loads proposed in the previous paper in which problems of the maximum response calculation of piping systems to multiple support excitations were discussed. In this paper, experimental and numerical investigations are carried out in order to confirm the validity and feasibility of the proposed method. Using a simple Z-beam shaped piping model for a shaking test, the maximum response of piping in the fundamental mode is measured and the combination law is applied to various correlation cases among two vibrational loads. From the experimental results, it has been made clear that the proposed method could be reasonable by comparison with other combination laws, like the square root of the sum of the square (SRSS) method.
