The multilayered soil-structure seismic interaction and structure vibration mechanism

Abstract

The morphology of subsoil influences to soil-structure interaction and it makes complex to predict seismic structural stability. The structural elements seismic response associate to soil-structure interaction is required expansive investigation with considering soil morphology. The main objective of the present study is to identify influence of near-fault ground motion mechanism reach to the structure element for evaluate strain energy modification due to the morphology of subsoil and developing load and displacement on the structural element with built-up synthetic subsoil for soil-structure seismic interaction design. The results of the numerical simulation revealed that the (i) displacement mechanism and applied seismic load of the structural element, (ii) strain energy modification and (iii) the structural vibration patterns of continuous beam in a timber frame have been changed in associated to the soil foundation characteristics. The innovation of this study is the soil-structure interaction, the soil layers interaction, near-fault ground motion and mechanical properties of the soil at different location of the soil foundation are fundamental parameters to control continuous timber beam seismic design.
