Abstract
This study proposes a load combination method considering the correlation coefficient among support excitations for response analysis of multi-supported piping system. The traditional combination methods can lead to large errors depending on the combination of inputs because of neglecting the correlation among inputs. However, because this proposed method should lead to small errors regardless the combination of inputs, it is expected that designing comes more rational. In the simulation of single- degree-of-freedom system, the comparison of results of this method and traditional methods showed us the availability of this method. And, the simulation of two-degree-of-freedom system showed us the availability of using the combination method considering the correlation among modes in addition to this method.
