Recently, as the structural design has shifted to the performance design, seismic design considering soil-structure interaction becomes more important. In this study, it [...]

We expressed the average shear strain and stress of the target soil layer using observed absolute accelerations at upper and lower boundary surface in the target soil lay [...]

In microtremor observation, forces are inputted to multipoint of the system. However, input forces cannot be specified. The authors have proposed a new method to estimate [...]
