4. Simple method to estimate the amplification by surface soil
The precise numerical simulation of surface soil amplification is becoming practical with the progress of the numerical analysis methodology and accumulation of the information on the ground conditions. On the other hand, simple methods to estimate the amplification by surface soil are also studied for the purpose of the building regulation and so on. Among them, following thirteen papers are shown in this page.
