For seismic response analysis of multiple supported piping systems in industrial facilities such as nuclear power plants and petro chemical plants, several simple analysis methods have been proposed and discussed. However, most of them are about one input system because it seems difficult to apply multiple input. Although a simple method for estimating the multiple input response analysis for linear systems is also proposed, we cannot use for nonlinear systems. In recent years, the seismic design considering both nonlinear and multiple input problems has been focused on. Then, the purpose of this study is proposing a new method with considering these two problems. We got the response reduction effect by the difference of phases as a result from the experiment in order to compare with the simulated results and the experimental results.
