The Study of the Correlation between Ground Motion Input and Artificial Boundary Condition

Abstract:

It is documented that some confusions about ground motion input and artificial boundary condition in present seismic analysis affect engineering anti-seismic security evaluation, and that different treatment effects on security are so lack of verification that they are must be checked, discussed and made clear to get consensus. A study was conducted with a typical example with large FEM software ANSYS and comparison was made between the results of various ground motion input and boundary treatment methods and those of theoretical correct analysis. Study shows that ground motion input and artificial boundary condition is greatly correlative and that correct results can’t be got unless ground motion input and artificial boundary condition can be treated and matched properly.
