| Research Abstract |
For 3 dimensional nonlinear FEM models of the soil-structure interaction system used for high accuracy seismic safety assessment of the building, reduction of the computing time is a problem. For the purpose, it is efficient to shrink the analysis area by use of high accuracy wave boundary. In this study, the energy transmitting boundary, which is limited for the frequency domain analysis, is transformed to the time domain and applied analyses considering the nonlinearity of the building and it near field soil. By this method, the computing time is reduced to 1/10 comparing to the previous typical method.
